Question

Scientists try to explain how changes in substances take place. By applying energy, you can tear a sheet of paper into pieces of paper and cause a _______ in the paper?

1) change
2) transformation
3) reaction
4) modification

Answer 1

Tearing a sheet of paper results in a physical change, modifying its appearance without altering its chemical composition.

The Correct Option is; transformation

Step-by-step explanation:

By applying energy to tear a sheet of paper into pieces, you cause a physical change in the paper. Physical changes alter the appearance of a substance without changing its molecular structure. Tearing paper changes its size and shape, but it does not change the paper's chemical composition or the identity of the material itself.

A physical change occurs when the appearance of a substance is altered without changing its molecular structure. Tearing a sheet of paper into smaller pieces is an example of a physical change because it does not involve a chemical reaction or the formation of new substances. In this case, the paper remains the same, but its shape changes.
