ABSTRACT
Physical chemistry is the study of the relationship between physical and chemical phenomena. It deals with the multilateral studies of chemical reactions and their corresponding physical processes using theoretical and experimental methods of physics and chemistry. Physical chemistry as a boundary science covers the phenomena studied from several angles. It takes into account the nature of the interaction of atoms and molecules and thus examines complex and interconnected phenomena of the material world. All disperse systems are thermodynamically unstable, since they have a highly developed surface. As a consequence, such systems are characterized by the high value of free surface Gibbs energies Gm. Rehbinder drew attention to the delay in the diffusion of adsorption processes, during the flow of liquid solution from the zone of contact of converging solids. When the particles approach each other, the liquid from the thin part is mechanically squeezed out into thick layers.
