It depends on the pressure. At normal atmospheric pressure, the melting point of water is about 273.15 K.
Cold temperatures will, if cold enough, freeze water.

cold water
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
It expands when you freeze it
Because cold
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.
if the air gets cold enough it can freeze water.
cold
Because the enzymes in freeze with the cold and move a little bit but not much
Cold water freezes faster because hot water has to cool down to the freezing temperature before it can freeze.
