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

As p i = ( E V ) T , which defines the internal pressure of a liquid, it can be found that:

p i = n I b ( T ) N 2 α 2 V n + 1

where N is equal to the number of molecules

I is the ionization potential of the liquid

b ( T ) is a temperature dependent relation based on numerical constants of the pair summation from inter-particle geometry

α is the polarizability

V is the volume of the liquid

where for most non-polar liquids n = 1
