ideal gas law

A law relating the pressure (P), temperature (T), and volume (V) of an ideal gas. Mathematically, the ideal gas law can be written as:

pV = nRT,
where n is the number of molecules of the gas and R is the so-called gas constant.

The ideal gas law implies that at constant temperature (T), the product of pressure and volume (pV) is constant (Boyle's law) and at a constant pressure, the volume is proportional to the temperature (Charles' law).
