Abstract:

In this paper, two interface thermodynamics methods, the Guggenheim method and the Gibbs method, are introduced.The thermodynamic criterion of the two-phase equilibrium is established using Gibbs interface thermodynamics, and a new method for derivation of Kelvin equation is put forward based on the thermodynamic criterion of the two-phase equilibrium.

Key words: Kelvin Equation, Guggenheim interface thermodynamics, Gibbs interface thermodynamics
