Interaction potential of a saturated fluid
A complete description of a saturated fluid in terms of thermodynamic equations is correlated with the equivalent statistical theory. Although the macroscopic theory only provides mean values for parameters, it is shown that it can provide information on the liquid/vapour interface at the microscopic level in the form of a functional relation between the interaction potential and the interparticle distance. Since the potential energy of the system is associated with the internal system energy, it is possible to find the equilibrium interaction potential without any knowledge of the entropy, from measurements of temperature, vapour pressure, surface tension and the reciprocal densities of liquid and vapour.
