Surface tension and internal pressure of liquids

Abstract

An expression developed by Rosseinsky for relating surface tension and internal pressure is modified by considering the effect of curvature on surface tension of liqs. A new relation between internal pressure and superficial properties of liqs. has been obtained. The agreement between calculated results and the experimental data indicates that this relation is satisfactorily applicable to various liqs. in a wide temperature range.7

Key words: LIQUID, CRITICAL TEMPERATURE, SURFACE TENSION, INTERNAL PRESSURE, STATISTICAL MECHANICS, CURVATURE
