We have somewhat established that the dominant factor in hot water's
freezing faster than cold is evaporation. The hot water is at a higher
temperature, and thus evaporates more quickly. The remaining water
has a lower "thermal mass" and thus turns to ice sooner.
Now, what is this thing called evaporation? I believe that it is a mass
diffusion process rather than a heat transfer process. A body of water
will continue to evaporate until it has come to equilibrium with the
surrounding air. So here are some questions to ponder:
Will water evaporate faster into warm dry air or cold dry air?
What is the humidity in a freezer? Does it promote or hinder
evaporation compared to room air?
Does more water evaporate from a swimming pool on a cool night or on a
hot day? (Say that the pool stays the same temperature)
Let's get a good discussion going!!!

Nobody has responded on the nature of evaporating water. Is nobody
interested, or is it just not esoteric enough for you all? Once more I
pose the question:
Does water evaporate faster into cool or warm air?
[Any responses will be greatly entertaining]
