Surface tension and heat of the surface formation of liquids

Abstract

By the potential method, it was determined that regardless of the nature of the liquid, the surface tension coefficient is determined by [Formula: see text]. In this expression, [Formula: see text] is the specific heat of the surface formation, [Formula: see text] is the critical temperature. According to our approach, the specific heat of the surface formation (SHS) also depends on temperature: [Formula: see text] ([Formula: see text] — the specific heat of the surface formation at the mealting temperature, [Formula: see text] — thermal coefficent of SHS). In this research work, the temperature dependence of the surface tension coefficient was calculated for seven dissimilar liquids. It was revealed that the calculated values of [Formula: see text] are in satisfactory agreement with the available experimental values.
