In a Joule-Thomson process this quantity is conserved. This state variable is useful in analyzing chemical reactions with gaseous products, since work is required to make the change in volume. Equal to the energy of the system plus the product of pressure and volume, a reaction is said to be exothermic when the change in this quantity is negative. The Gibbs free energy of a system is given by subtracting the product of temperature and entropy from this quantity. For ten points, identify this thermodynamic quantity that is usually symbolized H.
