Question for the physics gurus

Since the specific heat of water ice is about twice that of air (and frozen food usually has a bunch of water in it), an empty freezer will change temp more quickly than a full one given the same amount of heat transferred. So I guess the power company knows what's up.

But yeah, operating on a day-today basis? I'm pretty sure it's a wash.
