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?

Bud · Answer 1

here we have to explain the use of the energy release by water to form ice in electrical ice-maker

The energy is conserved in the ice in the from of bond energy.

There remain hydrogen bonds in the liquid state of water but on addition of electrical energy in ice-maker the state of water changes from liquid to solid. In this change the volume of the water decreases and the hydrogen bond present in water become more stronger.

The potential energy released by the water is consumed in its ice form as hydrogen bond energy.

On addition of electric energy to form ice from water, the energy is used to form stronger hydrogen bond.
