Definition

A macroscopic equation that relates pressure (P), volume (V), temperature (T) and amount of substance (n) for an idealized gas by the relation PV = nRT, where R is the universal gas constant; it is a model-level statement valid when intermolecular interactions and finite molecular volumes are negligible.
