Van der Waals equation from the viewpoint of probability distribution and the triple point as the critical point of the liquid-to-solid transition
We show that a distribution of the type of the Bose-Einstein distribution describes the van der Waals gas, while the Fermi-Dirac distribution describes the van der Waals liquid. We present the construction of the binodal, the melting curve, and the liquid-to-amorphous-solid transition under negative pressure. The notion of correlation sphere and the two-scale picture on the Hougen-Watson diagram are used. © 2015, Pleiades Publishing, Ltd.
