Answer 1

$\huge\underline{\overline{\mid{\bold{\red{AnsWer}}\mid}}}$

Because at first the balloon is flat. But when we blow air into it, it grows in size, hence proving that air occupies space, which is a physical change. Blowing a balloon is a physical change because if we let the air out of the balloon it goes back to its actual state.
