State function

From Biocrawler, the free encyclopedia.

In thermodynamics, a state function, or thermodynamic potential, is any 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. (See the related Markov property.)

The following are a few examples of state functions:

• Temperature
• Pressure
• Enthalpy
• Entropy
• Heat capacity
• Helmholtz free energy
• Gibbs free energy
• Fugacity
• Refractive index
• Viscosity
• Thermal conductivity
