Coomber's relationship can be used to describe how the internal pressure and dielectric constant of a non-polar liquid are related.

As <math>p_i=\left(\frac{\partial E}{\partial V}\right)_T\,</math>, which defines the internal pressure of a liquid, it can be found that: <math display="block">p_i = n \cdot I \cdot b(T) \frac{N^2\alpha^2}{V^{n+1}}</math> where

• <math>N</math> is equal to the number of molecules
• <math>I</math> is the ionization potential of the liquid
• <math>b(T)</math> is a temperature dependent relation based on numerical constants of the pair summation from inter-particle geometry
• <math>\alpha</math> is the polarizability
• <math>V</math> is the volume of the liquid

where for most non-polar liquids <math>n=1</math>
