gas equation

n
(General Physics) an equation that equates the product of the pressure and the volume of one mole of a gas to the product of its thermodynamic temperature and the gas constant. The equation is exact for an ideal gas and is a good approximation for real gases at low pressures. Also called: ideal gas equation or ideal gas law

If Z less than 1, then attractive interactions dominate and the volume of the gas is less than that predicted by the ideal gas equation.
p] and replacing v with the ideal gas equation of state v = RT/p gives:
However, the ideal gas equation of state can be only derived from kinetic theory if assumptions of no attractive forces between molecules are made and volume of gas molecules is neglected [4, 5].
