Explanation:
Detailed explanation-1: -FREEZING When liquid water freezes, it releases thermal energy and turns into the solid state, ice. VAPORIZATION When water reaches its boiling point of 100ºC, water molecules are moving so fast that they break free of the attractions that hold them together in the liquid state.
Detailed explanation-2: -When solid ice gains heat, it changes state from solid ice to liquid water in a process called melting.
Detailed explanation-3: -In order for the molecules to actually separate from each other, more energy must be added. This energy, called heat of fusion or heat of melting, is absorbed by the particles as potential energy as the solid changes to a liquid.
