title: Semi-empirical description of the constant β in the equation of state for interfacial tension.
abstract: A semi-empirical expression for the constant, β, in the Equation of State (EOS) for interfacial tension is proposed that exhibits a dependence on the surface area, heat capacity and thermal expansion coefficient of each of the materials involved in the three phase equilibrium (at constant temperature and pressure). The "wetting function", which yields values between zero and unity as the contact angle, θ, varies from 0° to 180°, is also employed in the description of β. Empirical data is used to support that equation as well as the initially proposed relationship leading to its derivation that is based entirely on Classical Nucleation theory (CNT) outcomes and a "difference of the squares" correction term for the liquid-vapor and solid-vapor interfacial tensions.
