Answer 2

Answer:

Hi dude here is your answer.

Explanation:

To answer your question in a much better way, let us first see how do we define purity of a substance (in this case the Air which is in form of Gas):

The purity of gas is an indication of the amount of other gases it contains. A high purity refers to a low amount of other gases.

Now Air which is a common name for the Earth's Atmosphere is a mixture of 78.09% nitrogen, 20.95% oxygen , 0.93% argon, 0.039%carbon dioxide , and small amounts of other gases. There is an average of about 1% water-vapor.

Hence Air is not a pure substance, as it's a mixture of various elements in just the right proportion to sustain human life on Earth.
