Abstract

When two phases are in equilibrium, the density and chemical composition of each remains uniform up to the interface. Within the interface the thermodynamic densities are not uniform, but rather vary continuously from the values they have in one of the bulk phases to the values they have in the other. In Figure 1 we see a hypothetical profile of the density p as a function of the distance z perpendicular to the interface, in liquid-vapor equilibrium. Such profiles constitute what we may call the structure of the interface. We wish to determine this structure theoreticfally, and also the interfacial tension, and to relate the latter to the former.
