• State function — In thermodynamics, a state function, state quantity , or a function of state , is a property of a system that depends only on the current state of the system, not on the way in which the system got to that state. A state function describes the… …   Wikipedia

• Thermodynamic potential — A thermodynamic potential is a scalar potential function used to represent the thermodynamic state of a system. One main thermodynamic potential which has a physical interpretation is the internal energy, U. It is the energy of configuration of a …   Wikipedia

• Thermodynamic state — A thermodynamic state is the macroscopic condition of a thermodynamic system as described by its particular thermodynamic parameters. The state of any thermodynamic system can be described by a set of thermodynamic parameters, such as temperature …   Wikipedia

• Thermodynamic equilibrium — In thermodynamics, a thermodynamic system is said to be in thermodynamic equilibrium when it is in thermal equilibrium, mechanical equilibrium, and chemical equilibrium. The local state of a system at thermodynamic equilibrium is determined by… …   Wikipedia

• Thermodynamic databases for pure substances — Thermodynamic databases contain information about thermodynamic properties for substances, the most important being enthalpy, entropy, and Gibbs free energy. Numerical values of these thermodynamic properties are collected as tables or are… …   Wikipedia
