Heat

• Total Heat (Enthalpy): A thermodynamic quantity equal to the sum of the internal energy of a system plus the product of the pressure-volume work done on the system. h= E + pv where h= enthalpy or total heat content, E = internal energy of the system, p = pressure, and v = volume. For the purposes of this paper, h = sensible heat + latent heat. • Sensible Heat: Heat that causes a change in temperature. • Latent Heat: Change of enthalpy during a change of state. .
