blowing a balloon is a physical change as when you blow a balloon the balloon expands but the balloon remains a balloon .there is change in size but the material is same .
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 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

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 if we let the air out of the balloon it goes back to its actual state.

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).
