Cold water freezes faster because hot water has to cool down to the freezing temperature before it can freeze.
Cold air and hot water makes water freeze faster simply because the hot water is steaming and so the result is that there is less water to freeze. hot water = steam = less water less water = faster freeze cold air = faster freeze
cold water
It has been proven that hot water freezes faster than cold water.

Hot and cold water and a freezer and a timer or stopwatch
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.
The fact that hot water may freeze faster than cold is often called the Mpemba effect
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.
No. It takes longer to freeze because cold water is closer to it's freezing point.
cold water is best because it will freeze faster
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.
It freezes faster when it's hot, because the water precipitation makes the volume the water takes up less, thus allowing it to freeze faster. -Zero (Black ops user)
