Resumen de Mnemonic Device for Relating the Eight Thermodynamic State Variables: The Energy Pie

Jeffrey E. Fieberg, Charles A. Girard

• A mnemonic device, the energy pie, is presented that provides relationships between thermodynamic potentials (U, H, G, and A) and other sets of variables that carry energy units, TS and PV. Methods are also presented in which the differential expressions for the potentials and the corresponding Maxwell relations follow from the energy pie.
