Applied Aspects of Classical Thermodynamics. Part II: Some Consequences of Expressions for the Heat of Transition of Phase Transitions of the First Kind

Abstract

Using the previously obtained expressions for the heat of melting and the heat of evaporation, it is shown that there is no critical point on the melting line. An expression linking thermodynamic parameters at a critical point is obtained. It is shown that the calculated derivative at the critical point differs by no more than one or two percent. A fundamentally new expression for determining the volumes of atoms and molecules is also obtained.
