2.1 THERMODYNAMIC WORK OF ADHESION AND SURFACE FREE ENERGY
As is known, the state of thermodynamic system is characterized by thermodynamic potentials U (internal energy), F (free energy), G (Gibbs energy), H (enthalpy). In principle, any of these potentials, under corresponding conditions, is suitable for characterizing the energy of surface acid-base interactions since the work done by thermodynamic system in any process is accompanied by the loss of thermodynamic potential, which meets process conditions.
