WebEnthalpy is the sum of the internal energy of the system plus the product of the pressure of the gas in the system and its volume: H = U + PV. Therefore, enthalpy of a gas decreases with pressure at constant temperature. Enthalpy of the liquid phase at constant temperature remains constant for moderate pressures. H° = standard enthalpy (kJ/mol) S° = standard entropy (J/mol*K) t = temperature (K) / 1000. View plotRequires a JavaScript / HTML 5 canvas capable browser. View table.
