its based on what kind of jar it is in and and if u put the same amount of hot or cold water in it
Nope, no acid when water freezes, the water freezes by the very cold air turning cold water and cold air makes ice. It's like a recipe!
Cold water will freeze faster. Because the freezing point of water is 0oC, water that is closer to that point will freeze faster then hot water. This is because it will require less time to lower the temperature to the freezing point.
No - water freezes at zero degrees Celsius. The alcohol used in coolants freezes at a much lower temperature.
WikiAnswers is not going to do your experiment for you - that's cheating and it's wrong. Plus, you could be expelled for cheating. This is an easy enough experiment to do - just make a hypothesis of which one you think will dissolve the fastest and take 10 minutes to actually try it with hot and cold water. That's about how long it will take you to do the experiment yourself.
I believe hot water freezes faster because it is supercooled. Cold water is non-supercooled. When cold water freezes ice crystals form and float to the top, forming a layer of ice over the top of the water, so the layer of ice stops evaporation . While the hot water, which is probably no longer hot in the freezer,when it does freeze, it freezes throughout, creating more or less of a slush before freezing solid.
Cold water freezes faster then warm water.
cold water because it is closer to freezing point alredy when hot water has to be coled down.
Cold water, being the closest to freezing point, will obviously freeze the fastest. Hot water will freeze the second fastest, and salt water barely ever freezes, except in very cold conditions.
it gets cold and freezes

because water freezes at 0oC....so when the temperature is lower than that the water freezes.
When it is winter, it is extreme cold. so, the water freezes. after it freezes completely, you can walk on it
The process of water freezing into ice involves the temperature of water being lowered to 32 degrees Celsius. Hot water will take longer to freeze because the difference between the temperature of hot water and 32 degrees is greater than the temperature of cold water and 32 degrees.
Cold water would freeze the fastest because freezing is a physical change brought on by temperature change, and the temperature of cold water is closer to freezing temperature than boiling or room temperature water. Therefore, it would take less time to reach freezing temperature.
when water vapor freezes on a cold surface liquid waree forms immediately
I think the hot water bubble flies fastest than cold water bubble.
the salt prevents the water from getting cold
