The latent heat of water is 597.3 kcal/kg or 2500 kJ/kg at the temperature 0 C and barometric pressure 760 mm Hg. Enthalpy (h) of air is the thermal energy of that air expressed as sum of heat necessary to evaporate its moisture content at 0 C and to heat both the water vapour and dry air to its actual temperature, as expressed by the equation:

The specific heat of a substance also will change, with a change in the state of substance. Water is a very good example of this variation in specific heat. Specific heat of water is 1.0; but as solid ice, its specific heat approximates 0.50; and a similar value is applied to steam 0.48; the gaseous state of the water.
