Sounds as if you were trying to repeat the MpembaEffect. Apparently it was even known to Aristotle that to get a liquid to freeze faster, "warm it in the sun first".
Enter Mpemba (circa 1950s?) who had known that warm liquids freeze faster than cool ones when placed in the frig.
Much experiments and $$ later, the explanation is yet to arrive (maybe a Nobel?), but the optimum temps for the experiment are 35oC for the hot liquid and 5oC for the cold one.
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
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 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.
The fact that hot water may freeze faster than cold is often called the Mpemba effect
The materials needed for the experiment are: two containers to hold the water, hot water, cold water, thermometers to measure the temperature, a freezer to freeze the water, and a timer to record the time it takes for each to freeze.
cold water
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
Kinetic energy
yes
No. It takes longer to freeze because cold water is closer to it's freezing point.
normal water with salt
cold water is best because it will freeze faster

The purpose of conducting the "Does hot water freeze faster than cold water" project is to investigate and understand the phenomenon known as the Mpemba effect, which suggests that hot water can freeze faster than cold water under certain conditions. This project aims to explore this concept and potentially uncover new insights into the freezing process of water.
Yes it does. Cold water freeze slower than normal or hot water.
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.
