A thermodynamic potential (or more accurately, a thermodynamic potential energy) is a scalar quantity used to represent the thermodynamic state of a system. Just as in mechanics, where potential energy is defined as capacity to do work, similarly different potentials have different meanings. The concept of thermodynamic potentials was introduced by Pierre Duhem in 1886. Josiah Will… WebThe Gibbs potential G defined in Equation 7.3 is the complete Legendre transform of £ corresponding to both S and V being allowed to change. The three thermodynamic potentials given above are of great importance in the development of thermal physics as discussed in Chapters 3, 7, and elsewhere in this book.
