Fluids and Latent Heat of Evaporation

Latent heat of vaporization of some common fluids as alcohol, ether, nitrogen, water and more

The input of energy required by a change of state from liquid to vapor at constant temperature, is called the latent heat of vaporization. When a liquid undergoes a change to vapor state at normal boiling point, the temperature of the liquid will not rise beyond the temperature of the boiling point.

The specific latent heat of vaporization is the amount of heat required to convert unit mass of a liquid into the vapor without a change in temperature.

• 1 kJ/kg = 0.43 Btu/lb_m = 0.24 kcal/kg
