Ideal Gas Law

The Ideal Gas Law describes the behavior of a real gas with a density low enough or temperature high enough that it is far from liquefaction. The Ideal Gas Law can be expressed for Ideal Gases as follows:

pV = NkRT

where p is the absolute pressure of a gas,

V is the volume it occupies,

N is the number of molecules in the gas,

T is its absolute temperature,

and kR is the Boltzmann constant.
