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 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
Cold water freezes faster because hot water has to cool down to the freezing temperature before it can freeze.
It has been proven that hot water freezes faster than cold water.

yes
Hot and cold water and a freezer and a timer or stopwatch
warm water because the cold water will freeze the cell wall.
No. It takes longer to freeze because cold water is closer to it's freezing point.
normal water with salt
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.
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.
