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 would contain a variety of pure gases much like the air.
Greenhouse gas - Wikipedia
A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide and ozone.Without greenhouse gases, the average temperature of Earth's surface would be about −18 °C (0 °F), rather than the present average ...
