The Spherical Interface. I. Thermodynamics

Abstract

An extension of the Gibbs thermodynamic theory of spherical interfaces leads to generalized forms for the Kelvin relation and the Gibbs adsorption equation. Quantities of physical interest are calculated in terms of the particular dividing surface making the superficial density of matter vanish, frequently more convenient than the surface of tension. An expression is proposed for the work required to form a droplet which is not in equilibrium with the surrounding vapor.
