The Gibbs method in thermodynamics of heterogeneous substances carrying electric charges

Abstract

We combine Gibbsian method thermodynamic method for heterogeneous systems with electrostatics. The substances under study are those able to accumulate free (i.e., not dipolar) electric charges. We announce several key formulas related to the first and second energy variations for these macroscopic heterogeneous systems.
