Question

CFCs convert oxygen to ozone.

• A. True
• B. False

Answer 1

The correct option is A

True

Chlorofluorocarbons (CFCs) are gases used in refrigerators. When they escape into the atmosphere, they convert ozone$\left(O_3\right)$ to oxygen molecules$\left(O_2\right)$ and thus reduce the thickness of the ozone layer which protects us from the UV rays of the sun.
