7. Your friend shows you a special kind of paper that can change color. He says that it will change color if it is out in the sun. Can light from the sun cause the paper to change color?

b
Yes. The paper can take in energy from the light, causing it to change color.

No. Light is not a physical thing, so it cannot change physical things like paper.

change color.
