Based on the foundations of thermodynamics and the equilibrium conditions for the coexistence of two phases in a magnetic Ising-like system, we show, first, that there is a critical point where the isothermal susceptibility diverges and the specific heat may remain finite, and second, that near the critical point the entropy of the system, and therefore all free energies, do obey scaling. Although we limit ourselves to such a system, we elaborate about the possibilities of finding universality…

Thermodynamic Derivation of Scaling at the Liquid–Vapor Critical Point

This work shows that the functional dependence of the entropy as a function of energy and particle densities necessarily obeys the scaling form hypothesized by Widom, and predicts that the critical isotherm has the same functional dependence, between the energy and the number of particles densities, as the coexistence curve.

A specific form is proposed for the equation of state of a fluid near its critical point. A function Φ(x, y) is introduced, with x a measure of the temperature and y of the density. Fluids obeying an
