Theorem of corresponding states

Theorem of corresponding states

The theorem of corresponding states originated with the work of Johannes Diderik van der Waals in about 1873 [ [http://digital.library.okstate.edu/oas/oas_pdf/v56/p125_132.pdf "A Four-Parameter Corresponding States Correlation for Fluid Compressibility Factors"] by Walter M. Kalback and Kenneth E. Starling, Chemical Engineering Department,University of Oklahoma.] when he used the critical temperature and critical pressure to characterize afluid. According to van der Waals, the simple theorem of corresponding states indicated that all fluids, when compared at the same reduced temperature and reduced pressure, have approximately the same compressibility factor and all deviate from ideal gas behavior to about the same degree.
