Re: cooling water



There is a discussion in our building about which freezes faster warm water
or cold water. I seem to remember an article by Jerald Walker years ago
saying that warm water freezes faster. What are your ideas?

The way I see it, warm water doesn't freeze at all (unless it is
subjected to more than 10^4 atm of pressure, and the resulting solid
is then not ordinary ice anyway). At normal pressures only cold water
freezes.
