Ice Skating Anyone?

Winter is the time for ice skating and although most ice skating today is done on a rink, it is still a past time that occurs on lakes and ponds. So, have you ever stopped to think about why water freezes on the top of the lake's surface and not at the bottom of the lake? (No is not because 'otherwise the fish in the lake would freeze'.)


Hint: The answer to this question depends on the temperature dependence of the mass density of H2O. BruceS
