The Thermodynamic Analysis on the Surface Tension and Specific Surface Free Energy of Liquid

This paper analyzes the surface tension and specific surface free energy of liquid and discusses their microstructure mechanism. The analysis indicates that surface tension of liquid is related to the liquid surface problem in terms of force and surface free energy is connected with the liquid surface problems regarding energy. At the molecular level,the surface tension involves macroscopic conduction of the molecular interactive force. The surface tension results from the liquid surface hole and the specific free energy is attributed to the work of molecular interaction force. So both of them have something to do with the molecular interaction force.
