Gas - Wikipedia

Gas - Wikipedia

Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma).. A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).A gas mixture, such as air, contains a variety of pure gases.
