In chemical engineering, open-system energy balances are done over this quantity, which, for a monatomic ideal gas, equals "⢸ve-halves times RT."
The departure function for this quantity always includes a "Z minus 1" term but not a "log Z" term. Refrigeration cycles are trapezoidal on phase diagrams plotting this quantity against pressure. The Maxwell relation derived from this quantity sets "partial V partial S" equal to "partial T partial P." It is the Legendre (leh-ZHAHN-druh) transform of internal energy with respect to volume. In chemical engineering, open-system energy balances are done over this quantity, which, for a monatomic ideal gas, equals "⢸ve-halves times RT." Its partial derivative with temperature is de⢸ned as the constant-pressure heat capacity, and it equals the Gibbs free energy plus temperature times entropy, or "U plus PV." For 10 points, what thermodynamic potentialÂ—a state function according to Hess's LawÂ—is symbolized H?
