text: Coomber's relationship can be used to describe how the internal pressure and dielectric constant of a non-polar liquid are related.
  As , which defines the internal pressure of a liquid, it can be found that:
  where
  * is equal to the number of molecules
  * is the ionization potential of the liquid
  * is a temperature dependent relation based on numerical constants of the pair summation from inter-particle geometry
  * is the polarizability
  * is the volume of the liquid
  where for most non-polar liquids
