Parameters of the Ultimately Thin Surface Layer of Liquid Argon

A procedure has been proposed for calculating the smallest possible thickness of the surface layer in a one-component liquid/saturated vapor system. A model of the layer homogeneous with respect to the pressure tensor has been considered. The smallest thickness of the surface layer and the molar vol...

Description
Summary:A procedure has been proposed for calculating the smallest possible thickness of the surface layer in a one-component liquid/saturated vapor system. A model of the layer homogeneous with respect to the pressure tensor has been considered. The smallest thickness of the surface layer and the molar volumes for the surface layer regions adjacent to the liquid and vapor phases have been calculated for liquid argon in the saturation line within a range from the triple point to almost critical temperature. Using published information as an example, it has been shown that the data on the distribution of the substance in the surface layer can be brought to the parameters of the proposed model.
