The essential problem in treating surface tension is to obtain an adequate physical description of the interaction of system particles in the highly inhomogeneous interface between the homogeneous bulk phases of a fluid. Every theory has to deal with the density profile in the interface, and the success of a theory depends on the particular model on which the profile is based. The mean molecular field theory according to van der Waals allows the free surface energy, and hence the surface tension of a fluid, to be calculated from its bulk densities and vapour pressure.
