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.

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
yes
Kinetic energy
No. It takes longer to freeze because cold water is closer to it's freezing point.
normal water with salt
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 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.
