If you wanted to convince someone that the air is something and not nothing, what could you do?

just tell them to close their nose for a few seconds,I mean tell them to stop breathing for a while...they will themselves understand the worth of air!

have a nice day

Air is made up of 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and other gases in smaller amounts. All these elements are made of atoms. Atoms make up every living and non-living thing in this universe, air included.
