A physical change
Physical change of the paint, not the door.
the difference between a physical change and a chemical change is that a physical change is usually reversible whilst a chemical change is not reversible.
A physical change is reversible, a chemical change is not.
Physical... chemically, it's still the same substance,
Physical, because the balloon did not have a change in its chemical composition when it broke.

no, bursting of balloons is a physical change as the only change that occurs that that the shape of the balloon changes . Coming out of air is not a chemical change.
When thinking of a balloon, it's best to think of two different chemical compounds that do not mix, the balloon itself and air. What makes the balloon pop is that the pressure of the air exceeds the force of the chemical bonds of the balloon. In order for a chemical reaction to take place, you need to start off with one set of chemicals that become a new set of chemicals.However, when a balloon pops, no new chemicals are created. All that happens is that the electron bonds of the compound we know of as the balloon break.
