文摘

We expand the Van der Waals equation into its Taylor’s series form, and then modify the fourth order expansion by changing the constant Virial coefficients into their analogous ones. A more precise result about the law of corresponding states has been obtained. The law of corresponding states can be expressed as: in terms of the reduced variables, all fluids should obey the same equation with the analogous Virial coefficients.
