Question

An electric kettle uses electrical energy to boil water. Energy from the electricity is transferred to the water, heating it up. An electric ice maker also uses electrical energy, but it freezes water to form ice. Since energy can’t be created or destroyed, and water loses potential energy when it freezes to form ice, what happens to the energy put into the ice maker and the energy released by the water?

Answer 1

The energy input into the icemaker is used to drive the cooling system. The equipment has a radiant that requires to be run by electricity.  Liquid ammonia in the radiant tubes of the icemaker pick up heat from the water and evaporate. As the ammonia evaporates and moves to the radiator, the action of the fan cause it to lose heat to the environment. The ammonia cools and becomes liquid and moves back to collect more hest from teh water. This cycle continues unilt the water turns to ice.
