Question

define matter? justify that air is matter

Answer 1

Anything that occupies space and have weight is called matter.
Air is a matter because air occupies space and have weight. We can justify it by an example:-
When we fill air in a balloon and keep it to weigh it have some weight.
when we fill up air in a balloon the empty space gets filled up with air filled.

Answer 2

Hi friend,

Matter is something which occupies space and has mass.

Matter has three main states and 5 state of mater normally-

•Solid
•Liquid
•Gases
•Plasma
•Bose-Einstein

Air is a matter and we can prove that by this simple activity-

Inflate a balloon and then tie it by making a knot then the balloon is occupied by air and you can't fill more air in it as the balloon is totally occupied by air and thus air occupies space.

Hope it helps...!!!
