I wasn't 100% sure that my claim that everything in a freezer reaches the
temperature the freezer is set at (should be 0 degr. F), so I submitted my
question to Ask a Physicist (is there anything that's not on line???):

"QUESTION:
In a home refrigerator freezer set to 0 degrees F, assuming all the contents
have enough space to give up their heat, will all the contents eventually end up
at 0 degrees F? I'm aware that not everything freezes (which I read as "becomes
solid") at 0 degree F, so some of the freezer contents could still be liquid or
flexible (as in sports gel paks). If not all the contents go below 0 degree F,
why not? Thank you very much.
"ANSWER:
In an isolated system, which we assume the inside of the freezer approximates,
everything will eventually come to thermal equilibrium. That is, everything
will eventually have the same temperature."


So ice cubes and gel paks would be the same temperature.
