Is Air Matter?

Yes, Air is matter. Matter is the substance or material of which all things are made. Matter has mass. Matter has volume. Air weighs very little, but takes up a lot of space. Air is still matter. If you put a balloon in an empty bottle and try to blow it up you cannot. This is because the air in the bottle has nowhere to go. But, when you poke a hole in the side of the bottle the balloon can be blown up, because it pushes the air out through the hole. This means that air is matter.
