I think it’s more like hot water freezing faster than cold war, a notion I had heard once and was ridiculed for repeating. Well, guess what...? Hot water can freeze faster than cold water.
This can only be a description of a case where greater evaporation occurs in the hot water, until it is reduced to a smaller amount of water than the original "cold water" at the same temperature, and so freezes faster due to its lesser volume.
So the claim rests on rhetorical ambiguity.
[[Hot water can freeze faster than cold water.]]
Well yeah- if you put the hot water i nthe freezer and leave the cold water at room temp :)
