Air is nothing but a mixture of a variety of gasses. The air in the atmosphere consists of nitrogen, oxygen, which is the life-sustaining substance for animals and humans, carbon dioxide, water vapour and small amounts of other elements (argon, neon, etc.). Air is the general name for the mixture of gases that makes up the Earth's atmosphere. This gas is primarily nitrogen (78%), mixed with oxygen (21%), water vapor (variable), argon (0.9%), carbon dioxide (0.04%), and trace gases.
