The criticalexponents predicted by this equation are identical to those predicted by the Ising model, placing it inthe universality class of mean field theories.
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.
At the critical point, this equation predicts a compressibility of three-eights.
