Coomber's relationship
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
