Question

Carbon dioxide is heavier than air.

• A. True
• B. False

Answer 1

The correct option is A True

Use of carbon dioxide -

• Carbon dioxide $\left({\mathrm{CO}}_2\right)$is neither combustible nor a supporter of combustion.
• It is used in fire extinguishers to put out fires.
• It is heavier than air, so it settles and forms a blanket over the fire and thus cuts off the supply of oxygen.

Therefore, the given statement is true.
