Real Gases; The van der Waals Equation The gas laws and the ideal gas equation of state exactly predict the properties of ideal gases which do not actually exists. Their usefulness arises from the fact that real gas properties are close to the ideal gas properties. From the kinetic theory of gases, the ideal gas equation of state was obtained by neglecting intermolecular forces and assuming that the gas particles were point masses (i.e., they occupy no volume). Therefor one sees that ideal gases are gases that have no intermolecular forces and occupy no volume. When this is satisfied one has (60) where the subscript id on the P and V indicate ideal gas values of P and V. The postulat
