    it is because after blowing a balloon it bursts . when it bursts it reduces its size and then bursts. change of size can prove that blowing a balloon is a physical change

    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.

      It is  a  physical change  as   it  can be  reversed  and no  new substance is  formed
    Only  the size is  changed not  the  composition
    The  balloon remains a balloon only

    Blowing a balloon is a physical change because only the size of the balloon changes , no change in chemical properties of the balloon occurs (no new substance is formed).
