By definition, matter is anything that takes up space and has mass. When I blew up a balloon, the balloon expanded. This proves that the air inside takes up space. When I compared the mass of 2 identical balloons (one filled with air and one empty), the one with air had more mass. Because the balloons were identical, the difference in mass is attributed to the air. My evidence shows that air takes up space and has mass. Therefore, air is matter.
