To evaluation of the state of the own macroscopic force field of liquids

Abstract

The work analyzes both literature data on the dependence of the internal liquid pressure on thermodynamic parameters of state and theoretical ideas of the nature of the internal pressure. The analysis enables the formulation of a hypothesis: the temperature coefficient of the internal liquid pressure corresponds to the state of its force field and the dynamics of this coefficient follows the course of changes in the macroscopic force field of liquids. The hypothesis underlies the construction of a scale of states of the own force field of liquids. To substantiate this scale, and consequently, the formulated hypothesis, the scale is verified with respect to water. A unified scale of states of force fields of associated liquids is proposed.
