Abstract

The results obtained in studying the temperature dependence of parachor are presented. The concepts of the parachor at the critical point and reduced parachor are introduced. The approach based on scaling principles and the assumption of a universal character of changes in crossover functions at critical exponents was used to obtain a universal temperature dependence of the reduced parachor. The dependence of the parachor at the critical point on the critical molar volume was established. The constituents of parachor were determined for halogenated hydrocarbons.
