There are many examples in nature of frozen moving water(frozen rivers, frozen streams,etc). How does the movement and turbulence of water affect its freezing point? If in a cold room kept at -1 degree centigrade we have two bowlsne bowl has one liter of water and the other has one liter of constantly stirred water(one revolution/second). Initially both bowls are at 20 degrees centigrade, but the surrounding temperature of the room(-1 degree) will cause the unstirred water to freeze solid. Will the stirred water also freeze but take a longer time or will it never freeze? If the stirred water never freezes is the reason that stirring creates a small amount of friction in the water slightly raising its temperature, so that the water never falls to -1 degree centigrade. or Is it simply mechanical? Tiny ice crystals form and try to grow, but they are broken up by the stirrer and the water doesnt have a chance to freeze. Surely at very low temperatures, -40 degrees centigrade, any stirring at any speed will not prevent freezing.
