Description: It is proved that the physical concept of liquid surface tension is a part of the concept of internal energy. The physical model of liquid evaporation and formula obtained for calculating surface tension of the liquid are suggested. The formula was tested on reference values for 64 substances in the temperature range from āˆ'253 to +200 degrees Celsius. A uniļ¬ed concept for physical notions of surface tension and the internal energy of the liquid is also obtained. A physical model is agreed with the views of the other authors. The result of this model is formulas for calculating values of speciļ¬c heats for one- and two atomic gas. It was proved that surface tension is a part of internal energy. As a result a theoretical model is suggested and a theoretical calculation between surface tension and temperature is established. This dependence is confirmed by calculation of empirical data from the reference manual of thermophysical properties.
