Abstract

The thermodynamic characteristics of a non-spherical interface are considered. Two definitions of surface tension and their relationship are analysed. It is shown that the classical Gibbs definition has a clearer physical meaning. The hydrostatic approach to the determination of the surface tension and to the first and second bending moments of an interface is applied. Within the framework of this approach the generalized Laplace equation is obtained and the strict definition is applied to the surface of tension.
