Question

Explain how ${\mathrm{CO}}_2$ is able to control fires.

Answer 1

Carbon dioxide$\left({\mathrm{CO}}_2\right)$ as a fire extinguisher:

• Carbon dioxide is stored in liquid form in a fire extinguisher.
• When it is released it expands rapidly and covers the entire area like a blanket and disconnects the supply of oxygen to fire, which is the supporter of combustion.
• Also, carbon dioxide has a much lower temperature, so when it covers the fire it brings down the temperature rapidly thereby extinguishing the fire.

So, ${\mathrm{CO}}_2$ gas is used as a fire extinguisher.
