Answer 1

Answer:

1)Take a balloon and blow it up (fill it with air, that is, don't explode it.) As the air enters the balloon from your lungs, the air (which is a gas) takes up space in the balloon. The balloon expands because the air inside needs to take up more space. So that is how you can see that air takes up space.
