What are the characteristics of air?

Answer by  serendip (408)

Air is made up of the gases nitrogen, oxygen, carbon dioxide and water vapor. It has no definite size or shape. You can feel it moving (wind). When contained, like in a balloon, it expands when heated and contracts when cooled.

Air is just the moment of elements like oxygen and carbon dioxide moving from low concentrations to high concentrations. The sun heats up these air molecules and makes them move.

You can feel air in the form of wind and temperatures. You can smell air in the form of fragrances.

Some of the different characterists on air would include the molecules that make air. The two molecules include hydrogen and oxygen. These two molecules do come together and they form air. If the two are not combined then they will just be seperate and now amount to anything at all.
