Question

Is crumpling a sheet of paper a physical or chemical change? Why?

Answer 1

I believe it is a physical change. Crumpling a sheet of paper does not change any properties of the paper and it does not form a new substance it must be a physical change. It is only the shape or form of the paper that is being changed. Hope this answers the question.

Answer 2

Physical, you are not changing the chemical makeup at all
