A systematic continuum approach is proposed to develop models of moving interfaces. The approach uses a zero-mass Gibbs dividing surface as an approximation of real three-dimensional interfacial region, introduces quantities representing the net action of two bulk phases on the interface, and employs the second law of thermodynamics to provide required constitutive equations. To demonstrate the approach, a general thermodynamic model is developed for two-dimensional moving interfaces.
