Definition

A cubic equation of state for pure substances that models pressure as the sum of a repulsive (excluded-volume) term and an attractive term whose magnitude depends on temperature (commonly via a 1/√T dependence), intended to represent P–V–T behaviour with modest accuracy for nonpolar or weakly polar fluids at moderate conditions.
