Discuss the process of the freezing of water from the point of view of the first law of thermodynamics. Remember that ice occupies a greater volume than an equal mass of water.

Freezing is a phase transition, which is defined as, a transformation from the disordered liquid phase to the ordered solid phase. As, you remove heat from water at 0 ̊ C, the water freezes into ice rather than becoming colder. Because the water molecules release energy as they bind together to form ice crystals, the water releases heats at it freezes. The heat released when transforming a certain mass of liquid into solid, without changing its temperature, is the latent heat of melting.
