Which freezes faster water or water with sugar

In this particular case, should the experimenter concern herself with what freezes faster, or the temperature at which the freezing occurs? The question of what freezes faster implies that if a sample of water and a sample of sugar water were placed in a freezer simultaneously, then one of them would freeze before the other The sugar water froze faster than the plain and salty water. However, the salty water was the least frozen one of all Sugar water freezes faster than salt water, because salt has more molecules than sugar. Normally, water freezes at 32°F, however, when a substance is added to the water, it lowers its freezing point. This is not because of the chemical nature of the substance being added, but rather the number of molecules plain water will freeze faster than sugar water. The sugar in the water works like an anti-freeze Water will freeze faster than liquids with salt or sugar in them. Some liquids freeze faster than others because of viscosity, or thickness of the liquid. Viscosity is the resistance of a liquid to flow. For instance, a cup of honey will take longer to pour than a cup of water because the honey has higher viscosity

Science Projects on What Freezes Faster: Water or Sugar

Which freezes faster, water or salt water? Question Date: 2013-01-26: Answer 1: While pure water freezes at 0°C (32°F), salt water needs to be colder before it freezes and so it usually takes longer to freeze. The more salt in the water, the lower the freezing point. Very salty water freezes at around -21 °C, or about -6 °F Water with salt only freezes at the temperatures 21 degrees Fahrenheit and under. Water with sugar freezes with temperatures -31.836 degrees Fahrenheit and under. 1 gram of a solute per liter decreases the freezing point by -33.696 degrees Fahrenheit. The more of the solute added the more the freezing point decreases

Why hot water freezes faster. When water is frozen, a similar reaction happens. The molecules initially tighten up and bind together to create a solid form. Since hot water's molecules are already tightened up, it has a head start on looking it should in its frozen state. Cool water would take time to reach this point Sugar Added to Freezing Water When sugar is added, the sugar molecules dissolve into the water. The number of water molecules captured by the ice during the freezing process also decreases. This causes the freezing temperature of water to decrease and the process takes longer. How does water freeze

freezes first since it gets to its freezing temperature, while the sugar water and slat water are still getting colder. It also shows that the freezing point of salt water is lower than that of sugar water Watch on As the video above explains, the phenomenon of hot water freezing faster than cold water is known as the Mpemba effect, named after Erasto Mpemba, a Tanzanian student who in 1963 was making ice cream as part of a school project. The students were meant to boil a mixture of cream and sugar, let it cool down, and then put it in the freezer I froze liquids like vinegar, milk, coke, juice, lemon juice, salt water, sugar water, bottled spring water, distilled water and sparkling flavored water to see which one froze faster. I predicted the distilled water would freeze fastest because it has no added ingredients but in my first two trials the carbonated sparkling water froze first Salo does her science experiment for class. The experiment was to see what happens when water freezes, both as plain tap water and as a sugar solution. The.. The Mpemba effect is a catch-all term for possible cases in which hot water appears to freeze faster than cold water. The phenomenon is temperature-dependent. There is disagreement about the parameters required to produce the effect and about its theoretical basis

The plain water will freeze the fastest because there is nothing interfering the freezing process. The sugar water will freeze next and the salt water will be the last to freeze. Why does the sugar water freeze faster than the salt water Warm water freezes faster than cold water. This is because when water is warmed up, the oxygen it contains is released, and the less oxygen water contains, the faster it freezes. Cold water contains much more oxygen than warm water and, in order for the cold water to freeze, it must lose some of this oxygen What you guessed about the two kinds of water. 2. What you did with the water. 3. Which water froze faster, salt or fresh water. 4. If your guess was correct about the two types of water. Be careful to obey all the school rules for your science fair project water report. Two paragraphs per grade level will do if you weren't given how long it.

No. Salt water has a lower freezing point than that of sugar water; it will take more time to freeze. The presence of a solute lowers the freezing point when compared to pure water. This phenomenon can also be explained by the colligative property of solutions Water freezes at 32 degrees Fahrenheit (0 degrees Celsius), but when a solute such as sugar is added, the freezing point changes. The sugar molecules prevent the water from making hydrogen bonds, which are required for solidity, and the water has to become even colder before it reaches its freezing point Saturated salt water freezes at a lower temperature than saturated sugar water, which freezes at a lower temperature than plain water. So plain water will freeze first, then sugar water, then salt water

Does Salt Water or Sugar Water Freeze Faster

  1. The Physics of Why Hot Water Sometimes Freezes Faster Than Cold Water Tanzanian high school student Erasto Mpemba was making ice cream with his class when he impatiently put his sugar and milk.
  2. The sugar dissolved into the water which made it freeze faster than the baking soda. Although the salt dissolved in the water, it was preventing the water from freezing because it thaws the ice. Conclusion: My data supported my hypothesis because I said the order of freezing would be water, sugar water, baking soda water, salt water and it was
  3. Plain water freezes at 32 degrees F, but when sugar, or salt, or other solutes are dissolved in it, the freezing point gets lower. This link says the standard 4:1 solution starts freezing at 26-27 degrees F. I assume that a 3:1 would have an even.
  4. utes. I think that my experiment was fairly accurate. I equally measured out every liquid and made sure my freezer was the same temperature every time. I feel that I could have used more liquids to improve the experiment or used an empty freezer.In the end, my hypothesis was correct
  5. Each mole of sucrose in a kilogram of water would depress the freezing point of water by 1.85 degrees C, according to Blagden's law (which is more valid at low concentrations). The molecular weight of sucrose is 342 grams/mole. So 2% sucrose should freeze around -0.1 C and 10% sucrose -0.5 C
  6. My son noticed that the thicker liquids were much slower to freeze than their thinner counterparts. That's when I jumped in with the word viscous. We talked about how the water, milk , vinegar ,and apple juice froze faster because they all have lower viscosity than the dish soap , ranch dressing and chocolate syrup

Science Projects on What Freezes Faster: Water or Sugar Water? State and municipal governments frequently dispense salt as a de-icing agent on roads. It works by effectively lowering the melting temperature of the ice. This phenomenon --- known as freezing-point depression --- also provides the basis for a variety of science projects In 1963, Mpemba's class was dissolving sugar in boiling milk to make ice cream. Hot water freezes faster than colder water simply because less of it has to turn into ice. If you've ever been.

which freezes faster sugar water or plain water? Yahoo

Sugar Water (C6H12O6 'aq') will freeze faster because it is a molecular compound dissolved in water and will not ionize (split up into its elements) in water. NaCl 'aq' will make water harder to freeze because it does split up into Na+ and Cl-, doubling the normal rate of freezing The point of this experiment, in addition to learning whether salt or sugar dissolves faster in various liquids, is to learn how molecules interact in a solution. As you saw in the preceding illustration, the water molecules take up most of the room in the container All things being equal, cold water freezes faster. It takes time for the energy contained in a hot object to be transferred to a cold object. However, the rate of heat transfer is proportional to the temperature difference between the two objects, so hot water will lose heat faster than cold water. In other words, if you have water at 90.

What type of liquid freezes the fastest science experiment

  1. Another situation in which hot water may freeze faster is when a pan of cold water and a pan of hot water of equal mass are placed in a freezer compartment. There is the effect of evaporation.
  2. The Mpemba Effect is the phenomenon whereby hot water can, under certain conditions, freeze faster than cold water. Scientists have identified a number of factors to explain the Mpemba effect (conduction, evaporation and convection) but so far all the theories are only speculative
  3. As salt lowers the freezing temperature of water (hence why salt is used to melt ice in roads and walkways, etc) with all other factors being the same sugar water would freeze faster.Of course, plain/pure water would freeze faster than either, and water that has been heated first will freeze faster than cold water. :
  4. Salt water boils slightly faster than sugar water. In actuality, both of these substances raise the boiling point of water, making it take longer for the water to begin to boil, according to Serious Eats. Because salt and sugar are dissolved solids, they increase the boiling point of water by less than one degree. The effect of salt making.
  5. I think water is going to freeze faster,because water has no ingredients in it, but the other liquids have one or more ingredients in them. Variables Independent Variable All the liquids are different kinds. All the liquids have different ingredients. Dependent Variable The time it takes all the liquids to freeze. Controlled Variabl
  6. Therefore, water freezes faster than cold water in which the transformation from a randomly-arranged water clusters costs time and energy. But as with all the explanations that have come before this one, we're going to need to see more proof before we can know for sure that this - or a combination of factors - is truly at play in the Mpemba.

Sugar water freezes faster than salt water. water will freeze faster than either salt, or sugar water. What freezes faster salt water or water Hot water freezing more quickly than cold water is known as the Mpemba effect. So, why does the Mpemba effect occur? First, all water evaporates, which means that the liquid (water) disappears and becomes a vapor, or gas. Hot water evaporates at a much faster rate than cold water. This means that. Salt and sugar both causes freezing point depression, therefore making the ice melt faster, however salt is more effective as salt dissolves into two components and creates more interference in preventing water from freezing. Sand melts ice by absorbing heat which will bring it to a higher temperature than ice, causing it to melt Since the time of Aristotle, researchers and amateur scientists alike have batted about the counterintuitive theory that hot water freezes faster than cold. The notion even has a name: the Mpemba effect, named for a Tanzanian schoolboy who in 1963 noticed that the ice cream he and his classmates made from warm milk froze quicker than that made. Although Aristotle, Bacon, and Descartes all described hot water freezing faster than cold water, the notion was mostly resisted until the 1960's when a high school student named Mpemba noticed that hot ice cream mix, when placed into the freezer, would freeze before ice cream mix that had been cooled to room temperature before being placed in.

Discover the science behind solubility in this animation/live action video demonstration. A split screen shows the reaction take place in a glass of water,. Pure water freezes at 32°F (0°C). Water with salt (or any other substance in it) will freeze at some lower temperature. Just how low this temperature will be depends on the de-icing agent.If you put salt on ice in a situation where the temperature will never get up to the new freezing point of the salt-water solution, you won't see any benefit. For example, tossing table salt (sodium.

Water alone will boil at 100 degrees C but if you add anti-freeze to it you can increase the boiling point several degrees higher. adding vinegar and sugar to the water should increase the. Finally, supercooling may be important to the effect. Supercooling occurs when water freezes not at 0°C, but at some lower temperature. This happens because the statement that water freezes at 0°C is a statement about the lowest energy state of the water: at less than 0°C, the water molecules want to be arranged as an ice crystal 1⅓ cups for each quart of fruit. Dissolve sugar in hot or cold water. If hot, cool before using. Strength of syrup Water Sugar Yield Light 4 cups 1 cup 4¾ cups Medium 4 cups 1¾ cups 5 cups Heavy 4 cups 2¾ cups 5½ cups Sugar pack Juicy fruits and those that will be used for pies or other cooked products are often packed in sugar The Answer: The presence of sugar (or salt, or any other dissolved substance in water) does indeed lower the freezing point of water. This phenomenon, called freezing point depression, occurs because the particles of the dissolved substance interfere with the formation of the crystalline bonds between water molecules that give ice its solidity

A plain cup of water will freeze faster than the cups of water with the sugar and the salt in them. The independent variable in this experiment is the type solution (the sugar or the salt that is added to the cups of water). The dependent variable of this experiment is the amount of time it took each cup to freeze A freezing point depression of 1.86 °C occurs for every mole of solute added to 1 kilogram (kg) of water. In other words, if you dissolve one mole of sugar in 1 kg of water, water will no longer freeze at 0 °C, but rather will freeze at -1.86 °C Once the sugar is poured into the water, it is stirred. After stirring, the sugar can no longer be seen. Also after stirring, each student tastes the water. They both agree that the water tastes sweet. The weight of the water + glass + sugar is the same as the weight of the glass containing the mixture after the sugar was stirred in

  3. Ice cream is not rock hard because it contains sugar and water. In cooking salt is added to water so the water boils faster. A closed glass bottle of club soda cooled beyond 0 C remains liquid, but if uncapped freezes solid quickly

How does sugar affect the freezing point of water

Use one gallon of water per pound of prepared vegetable. Put vegetable in blanching basket and lower it into vigorously boiling water. Place lid on blancher and start counting blanching time as soon as the water returns to a boil. (The water should return to boiling within 1 minute, or you are using too much vegetable for the amount of water) When water freezes, the water molecules arrange themselves into special patterns,this is why we can sometimes see neat patterns in water crystals. If there is something like sugar mixed into the water (an 'impurity'), then it is harder for the water molecules to form the proper patterns. The sugar molecules are not the same shape or size as the. Hotter water freezes faster than colder water in some circumstances. This phenomenon is called the Mpemba effect. This effect is named after Erasto Mpemba when, in 1963 when he was in Secondary School, he observed hot ice cream mix froze before the cold ice cream mix Assuming equal temperature, ice melts faster in salt water because salt water has a lower freezing point than fresh water, so the ice cube will have to absorb less heat in order to melt in salt water than in fresh water.

Example #1: Freezing Water. Consider how the scientific method applies in this simple experiment with freezing water under two different conditions. Define Purpose: I want to know if water freezes faster on its own or with sugar added to it Diet soda uses artificial sweetener instead of sugar. Artificial sweeteners are more potent than sugar, meaning less sweetener is found in diet soda than sugar in an equivalently sweet regular soda. When solute is dissolved in solution, the solution undergoes freezing point depression: its freezing point drops. The magnitude of this effect is. When soda pop is produced, large quantities of additives (like sugar, colors, and flavorings) as well as carbon dioxide (CO 2) are pumped into water. These additives are called solutes and when solutes are added to a liquid such as water (the solvent), the freezing point of the water drops. By lowering the freezing point, soda has to reach a.

Ice at the freezing point of water actually has less energy or heat in it than water at the same temperature! WHAT MELTS ICE FASTER? There are many possible ways to melt ice. The simplest way is to just leave the ice to melt at room temperature. The heat energy in the warmer room works to break up the ice structure to turn it to water Anti-Freeze. Pure water turns into ice at temperature 0C (32F). What happens if you dissolve different chemical compounds in the water? Will salt or sugar prevent water from freezing or slow down the process? You'll find it out in this 4th grade project. It's simple and can be done in 24 hours

The energy in hot water is wound up so tightly that when it is released, it cools and freezes faster than cold water. How Much Faster Does Hot Water Freeze? It's hard to say. Water reaches its freezing point at 0° C (32° F), but the time it takes reach this point may vary. It's difficult to estimate how much faster ice cubes will form with. Water boils at 212 degrees Fahrenheit and turns to ice at 32 degrees Fahrenheit. Water conducts heat better than air. Salt water may make ice melt even faster than regular water. As water freezes it expands and covers more area. Water is made of two elements: hydrogen and oxygen. Hot water freezes faster than cold water Adding salt to water is going to do two things to water's physical properties: it will raise the boiling point and it will lower the specific heat. These two changes actually work against each other. Raising the boiling point will make the water boil slower. We'll need to get it to a higher temperature, which may mean a longer time on the. Adding salt lowers the freezing temperature of the water and for wintery roads, it means that the water won't freeze as easily. For our ice cream, it allows the temperature of the mixture around the ice cream to get colder. Since the ice cream isn't just water, it needs to be a little below 32°F to freeze

Does Hot Water Really Freeze Faster Than Cold Water

But, as Michael said, stirring it brings more water molecules into contact with the ice- and these newly-contacting-the-ice water molecules will have more energy to give to the ice than the cold water that used to be touching the ice, which will make the rest of the water colder and melt the ice faster Cold water freezes faster than hot water. Learning science is very observational at this age, so the full explanation may be too conceptual. Try this simplification: Hot water freezes more slowly than cold water because it has to transfer out more heat to freeze. 61 This is cool! Science investigation Science activity Look at the picture. Bottom line, while apple cider vinegar isn't going to keep your water from freezing much longer than plain water, except possibly when the temperature is above 28 and below 32, it will still provide numerous benefits and keep your chickens healthy through the winter, so keep adding it to your water a few times a week.. And as long as there's a bit of a breeze, your best bet is to use large. The cube in the fresh water is always bathed in the warmer water of the cup while the cold water from the melting cube sinks away from it. The cube in salt water is surrounded by its own very cold melt water, which is still less dense than the very salty brine. The cold melt water insulates the cube from the room temperature water around it Use this experiment to compare the time required for fresh and salt water to freeze. You will need the following materials: 2 paper cups salt tablespoon marker access to a freezer Fill both cups half full of water. Add 1 heaping tablespoon of salt to one of the cups and stir until the salt dissolves. Label the cups fresh water and salt water

Hot water really can freeze faster than cold water, a new study finds. Sometimes. Under extremely specific conditions. With carefully chosen samples of water. New experiments provide support for a. Sugar water can spread disease between bees visiting bee feeders. Whilst it's true the bees could pick up the diseases whilst visiting flowers its far less likely than if the bees are using a bee feeder. Flowers produce miniscule amounts of nectar. On the other hand a milk bottle top can contain the equivalent of more than a 1,000 flowers

52 Simple Science Experiments For Kids

The amount of salt in the water has a crucial role to play in determining its freezing point, so we need to find out how much salt the water contains in order to find out what its freezing point is. In case of sea water, the average salt content is 35 parts per thousand, and therefore, its freezing point is −1.8°C (−28.9°F) 1 cup sugar. Pinch of salt. 2 tbsp vanilla extract. Pour the milks into a sauce pan and place over medium heat, stirring occasionally. Whisk the egg yolks and then slowly add the sugar and salt. The mixture should be light in color and thick. Once the milk is hot, but not boiling, remove it from the heat. Next, temper the eggs

Ask an Expert: Freezing Carbonated Sparkling Water vs

Why does salt make ice melt faster? Salt lowers the freezing point of water. The freezing point of pure water is 32 degrees Fahrenheit/ 0 degrees Celsius. The freezing point of salt water is different depending on the amount of salt in the water, but for reference, the freezing point of ocean water is about 28.4 degrees Warmer water will dissolve more salt than cooler water, regardless of the type of salt you are using. If you are doing a formal experiment, you should record the exact temperature of your water. There is more space between the water molecules if it is at a higher temperature, which is why it dissolves salt better Allow 6 to 8 hours in the refrigerator for thawing a 1 pound package of fruit packed in syrup. Allow ½ to 1 hour for thawing in running cool water. Fruit packed with dry sugar thaws slightly faster than that packed in syrup. Both sugar and syrup packs thaw faster than unsweetened packs. Thaw only as much as you need at one time

Sugar and Ice: Freezing Plain Tap Water and Sugar Solutio

Although the saltiness of ocean water varies, this lowers the freezing point of ocean water to about -1.8°C or 28.8°F. So ocean water will freeze. Another factor that affects the freezing of ocean water is its ocean current. Ocean current can be described as thermal convection combine to create large-scale flows of ocean water Freezing point depression. the gist is that adding impurities to water will lower the freezing point. Chocolate milk's gotta have more impurities in it, right, and less of the water one could expect... I'm no h2ologist though, so don't take my word on it Water conducts heat away from the body 25 times faster than air because it has a greater density (therefore a greater heat capacity). Stay dry = stay alive! Steel conducts heat away faster than water ; Example: Generally conductive heat loss accounts for only about 2% of overall loss. However, with wet clothes the loss is increased 5x Ice cube trays are designed to be filled with water, then placed in a freezer until the water freezes into ice, producing ice cubes. Ice trays are often flexible, so the frozen cubes can be easily removed by flexing the tray. Twist ice trays have a simple spring-loaded mechanism with a lever that is used to turn the tray upside down and flex at the same time, such that the cubes that drop. Mpemba Effect: When Hot Water Freezes before Cold. by Ron Kurtus (revised 17 January 2019) The Mpemba Effect is a special phenomenon where hot water freezes faster than cold water.. The discovery of this effect was made by a high school student named Mpemba in Tanzania, Africa in 1969
