Rock is matter, water is matter, steam is matter.. Even you and I are matters as well! But what is matter?
Matter, is something that has volume (takes up space) and mass. Matter can be in 3 kinds of statements, which are solid, liquid and gas. There are loads of things that are considered as matters.. And now that you know how to manage whether or not a thing is matter, here's the question, IS AIR MATTER?
Air is in a state of gas, and according to the experiment Mrs.Smith has done during the class, which was blowing a balloon in a bottle with and with out a whole on the bottle. We proved that air does have volume (take up spaces). The balloon has gone bigger only when there was a whole on the bottle. Which means that the space in the bottle has already been taken by the air in the bottle, therefore, the balloon wasn't able to expend if there's no whole on the bottle to let the air in the bottle float out.
Okay, now that air has already fit in with 2 out of the 3 conditions of matter. The last condition is mass, does air has mass? According to the experiment, The balloon that is fulled with air is heaver than the balloon that is not fulled with air. Which has proven that air do have mass.
Therefore, as the result, is air matter?
The answer is, YES IT IS.
