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?
