Cohesion and Heat Capacity of Liquid Water from the Viewpoint of an Electrostatic Model

Abstract

The ion–molecular model of water, which assumes a high concentration of short-lived ions of Н3О+ and ОН– and their proton exchange with neutral Н2О molecules, indicates that water cohesion is achieved in the form of electrostatic interaction between oscillating ions and the molecular dipoles that surround them. It is shown that these oscillators with a frequency of 5 THz are responsible for the specific heat capacity of water.
