THERMODYNAMIC ORDERLINESS AS ONE OF THE ESSENCES OF THE INTERMOLECULAR STRUCTURE OF WATER

Abstract

The paper considers possible estimates of the structure of water from the standpoint of its entropy indicators, understanding their growth as the state of disorder of the system and its disorganization. The possible ratios of individual water molecules and their structural accumulations in the form of organized clusters are taken into account. The main message consists in the fact that an always structured and ordered system has a lower entropy than an unordered and less organized system. dependence on its structuring and conditional ratio of individual molecules and their clusters. The technique is based on the combinatorial method of “gluing” n molecules into indistinguishable clusters and detecting mixing entropy taking into account dynamic factorization (time factor), as well as fine dynamics of bonds between molecules within the cluster. H2O 1 ⋅ 10-12 It is capable of reducing the etropy of the liquid by 14.7 % to its standard value. And in very short intervals of the cluster life cycle (10-13–10-14 s), the effect of thermodynamic ordering practically disappears. For arguments regarding such calculated clusters in the composition of water, publications with experimental data on the structure of water obtained by methods of quantum-chemical analysis of possible configurations of hydrogen networks in the cluster are referred to (H2O)20, including in the interface mode of the orientation of water molecules at the boundary of the interfacial field and the corresponding orientation entropy, the decrease of which is confirmed only in the nearsurface ordered layer of water. It is shown that structured water at the boundary with biological systems represents a more thermodynamically ordered medium, for which there are short-lived molecular clusters that are unconditionally stable near biomolecules and affect biochemistry, electrical processes and mechanics of organic interactions. Such and other indirect dependencies, despite their locality, should claim criterion abilities in favor of argumentation for cluster structuring of water systems.
