Development of an equation of state for gases

WebThe equation of state then takes the form of an equation relating P, V, and T, such that if any two are specified, the third is determined. In the limit of low pressures and high temperatures, where the molecules of the gas move almost independently of one another, all gases obey an equation of state known as the ideal gas law: PV = nRT, where ... WebAn important empirical equation of state that provides a fairly good description of the properties of real gases at high densities is the van der Waals equation: Equation 1.2 is similar to the ideal gas equation in Equation 1.1 but with a pressure correction term a/V 2 , which increases in importance with a decrease in volume, and a volume ...
