Water from a liquid state has
internal energy in them that defines the translational and rotational energy of
the molecules of water. However, when water freezes, it slowly turns into solid
phase and therefore lesser temperature is applied to freeze the water
molecules. The energy that is lost in the liquid is transferred to the solid
state of the water. Even though there is little or no movement of water
molecules in the solid state, there is still internal energy of the water.
