The relationship between surface tension and isothermal compressibility in simple liquids

Abstract

Working on the basis of a theoretical equation for the surface tension of liquids recently deduced by Mon and Stroud, a semi-empirical relationship was obtained between this quantity and the isothermal compressibility which, through the performance of several approximations, will embrace some widely published relationships as special cases. The results agree satisfactorily with experimental data for the most characteristic simple liquids.
