We want to determine how much the room temperature increases when a kg of ice freezes. suppose you have a freezer that needs 1 j of energy for every 3 j of heat it removes. how much thermal energy must be removed from 1 kg of water at room temperature? how much electrical energy is used to freeze the ice? what is the total energy, including waste heat, that is dumped into the kitchen? if the kitchen contains 40 kg of air, how much will the temperature rise? what is the efficiency of the freezer? (the latent heat of water for freezing is 80 cal/gm°c, and the specific heat of air is about 0.2 cal/gm°c. we know you could look it up; we thought we'd save you the time.)
