www.rses.orgEntropy is harder to define. It is the ratio of heat content of a gas to its absolute temperature. It remains the same when a gas is compressed, if no heat is added or removed. When entropy is constant, the condition of the gas is called isentropic. SAMPLE DIAGRAMS . The most common type of pressure-enthalpy diagram is shown in Figures 1A ...

Phase transitions in the P − T phase diagram are described by the Gibbs enthalpy G(T,P,N), as defined by (5.11), which is itself a function of the pressure P and of the temperature T. G(T,P,N) changes continuously across the phase boundary when the transition is of first order. The entropy S and volume V, which are given by

The electrolysis of one mole of water produces a mole of hydrogen gas and a half a mole of oxygen gas in their normal diatomic forms. A detailed analysis of this process makes use of the thermodynamic potentials and the first law of thermodynamics.
