An ideal gas is a theoretical gas composed of a set of randomly moving, non-interacting point particles. The ideal gas concept is useful because it obeys the ideal gas law, a simplified equation of state, and is amenable to analysis under statistical mechanics. One mole of an ideal gas has a volume of 22.41 L at STP.


A hypothetical gas whose molecules occupy negligible spaces and have no interactions,and which consequently obeys gas laws .ex- nitrogen , oxygen , noble gases , etc
