At the critical point, this equation predicts a compressibility of three-eights.
At the critical point, this equation predicts a compressibility of three-eights. The criticalexponents predicted by this equation are identical to those predicted by the Ising model, placing it inthe universality class of mean field theories. It is derived using the hard-sphere potential. Aroundphase transitions, it incorrectly predicts oscillatory isotherms. This equation can be derived bytruncating the virial expansion at two (*) terms. One constant in this equation accounts for the excludedvolume of a particle, and another accounts for attractive forces. It adds two constants, a and b, to a lessaccurate law. For 10 points, name this improvement on the Ideal Gas Law, named for a Dutch physicist.
