Enthalpy is a fancy word for the total heat energy within a substance. Don't confuse it with entropy, which is the disorganization of energy in a system. We measure enthalpy in energy per mass unit, such as BTUs per pound. Enthalpy combines both the sensible and latent heat capacity; for example, it may represent the energy that it takes to evaporate the water contained in the air. (Water vapor is always present in the air, not just at boiling. Evaporation…
