Answer 2

Answer:

Air is a mixture of many gases and tiny dust particles. It is the clear gas in which living things live and breathe. There is no air in outer space. Air is a mixture of about 78% of nitrogen, 21% of oxygen, 0.9% of argon, 0.04% of carbon dioxide, and very small amounts of other gases.
