Coordination chemistry elasticity

The concepts of classical and quantum physics allow one, either exactly or with a certain probability, to predict the state of macrobodies or microparticles. In particular, this concerns mechanical movement regularities, which can be described by using spatial-temporal, coordinates, the vales of mass, velocity, pulse, wave characteristics, the knowledge of the fundamental t5q)e of interaction. However, there exist some processes whose features can be explained by neither classical physics nor quantum representations. E.g. the existence of bodies to them in different aggregation states, the appearance of elastic forces at deformations of systems, possible transformation of some compounds into others, etc. As a rule, these and similar processes are accompanied by transition of systems fi om one state to another one with changes in thermal energy. Just such processes and most general thermal properties of macroscopic bodies are studied by the section of physics and chemistry called thermodynamics [1, 2, 9-11].
