Which is true when a piece of paper is crumpled? * (17 Points)
O A. volume and mass increase
O B. volume and mass decrease
O C. volume and mass do not change
O D. volume might decrease or increase, but mass does not change

The correct option is;

C. The volume and mass do not change

Explanation:

We note that a piece of paper usually does not compress when load is applied on it.

Therefore, when a piece of paper is crumbled, the volume does not change as the paper only becomes folded thereby, reducing its surface area with a corresponding increase in thickness

The mass of the paper does not change as in the process of the paper being crumbled, the matter and therefore, the mass remains constant.
