# state, equation of

﻿
state, equation of
Any of a class of equations that relate the pressure P, volume V, and temperature T of a given substance in thermodynamic equilibrium.

For example, the equation PV = nRT, where n is the number of moles of gas and R is the universal gas constant, relates the pressure, volume, and temperature of a perfect gas. Real gases, solids, and liquids have more complicated equations of state. See also thermodynamics.

any of a class of equations that relate the values of pressure, volume, and temperature of a given substance in thermodynamic equilibrium.

The simplest known example of an equation of state is the one relating the pressure P, the volume V, and the absolute temperature T of one mole of a perfect gas; that is, PV = RT, in which R is the universal gas constant. Dense real gases, liquids, and solids have more complicated equations of state.
