Herein we study the classical thermodynamics of multicomponent elastic solids as open systems. By writing down explicit expressions for the heat form and the work form, a simple derivation of the fundamental thermodynamic equations for elastic solids as open systems is presented. In particular a formula is obtained for the heats of mass transfer of the chemical components. This paper ends with a rebuttal to the contention that heat can not be unambiguously defined for open, classical reversible systems.
