Thermodynamic Function of State

Any of the quantities defining the thermodynamic state of substance in thermodynamic equilibrium. Also called thermodynamic variable, state variable, state parameter. For a perfect gas, pressure, temperature, and density are the fundamental thermodynamic variables, any two of which are, by the equation of state, sufficient to specify the state. Quantities defined in terms of these, such as specific volume, potential temperature, etc., may also be used as thermodynamic functions of state. If the composition of the gas varies, this must be specified. Thus, some measure of water vapor is a thermodynamic function of state of the atmosphere. </dd>
