Thermodynamic Effects

The thermodynamic effects of correlations between the motions of molecules in neighbouring cells in the Lennard-Jones and Devonshire cell theory of liquids and solutions are calculated approximately, and found to be sufficiently small to be negligible for many purposes.

Kihara Potential

The Kihara potential has been applied to the Lennard-Jones and Devonshire cell theory in place of the Lennard-Jones potential. The expressions for the internal energy, heat capacity, and entropy, as well as the compressibility, are given in excess over those of a perfect gas. A comparison between experimental data and the present theory is made.

A critical discussion is given of the various theories of the liquid state, which give an explanation of the liquid properties in terms of the intermolecular forces. In § 2 the general properties of the equation of state of monatomic liquids and the melting and vapourpressure curve are given using the principle of corresponding states with molecular units. In § 3 these experimental data are compared with the theory of Lennard-Jones and Devonshire. The influence of a smaller co-ordination number is investigated in § 4, and in § 5 the difficulties in explaining the additive constant in the vapour pressure curve is discussed. The generalizations of the theory of Lennard-Jones and Devonshire, discussed recently also by Rowlinson and Curtiss, are given in a somewhat simplified representation, showing that the decrease of the co-ordination number can be obtained as a straightforward result of the application of statistical mechanics to the ‘lattice model’ of the liquid state. The transition of the solid to the liquid phase is discussed in § 7, starting with Lennard-Jones and Devonshire’s theory of melting. It is shown that the disordered ‘liquid’ state corresponds to a liquid with a co-ordination number 9, and that an explanation can be given of the melting-point formula of Simon. Finally, in § 8 attempts are discussed to base a theory of liquids on a calculation of the molecular distribution function.
