Development of an equation of state for gases
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 ... WebI. Pressure-Volume-Temperature Behavior of Pure Gases and Liquids More than a hundred equations of state relating the pressure, volume, and temperature of gases have been proposed according t o Dodge ( 7 ) , but only a very few of them have attained any practical importance as the majority do not represent the data with sufficient accuracy. I n this …
