Ideal Gas Law

up:: 034 MOC Atmospheric Physics

The ideal gas law is

where is the universal gas constant, and number of moles of a given gas.

It can also be written with respect to densities , since

where is the (macro) gas mass and the (micro) molar mass of the gas molecules.¹ Thus, it can also be written as

where is the specific gas constant (for a given gas).
