To crumple, bend, or tear paper is a physical change.
Because crumpling only changes something's shape, it is a physical change.
Physical. You're not doing anything to alter the chemical structure of the paper. If you soaked it in ethanol and lit it on fire before crumpling it, that would be a chemical change.

a change in size, shape or the state of matter is a physical change. True for A+.
Volume is a physical quantity not a change. However CHANGE in volume is a physical change.

It is a physical change because it can be reversed. All you have to do is weld the foil back together!

To deform and crumple in a collision
Heat raises the temperature of the material. If the change is small then there is only a physical change and allowing the material to return to its original temperature will return it to its original physical state.However, too much heat can result in chemical changes which are usually not reversible. For example, if you heat a piece of plastic enough it will crumple into a charred mass. That charred mass will not return to the pristine plastic.
A phsical change is something that can be changed but cant be changed back. for example: you can crumple a piece of paper but it is still paper. A chemical change means it has been changed perminetly so for example: If you burn the paper its ashes not paper. it was ashes but youy cant change it back into paper. Hope this helps :)
Well because the paper is flat and when you crumple it, it is changing and getting wrinkly and in a crumpled form,
