Question

5.A. Explain how CO2 is able to control
fires

​

Answer 1

Carbon dioxide is able to control fire as it acts like a blanket between oxygen in the air and the fire.

• Carbon dioxide is a heavier gas as compared to oxygen gas.
• Carbon dioxide gas acts as a blanket between oxygen and the fuel due to which a fire gets controlled.
• When we release carbon dioxide from a fire extinguisher, it expands and then it cools down. In this way, it also helps in cooling the fire.
