Explain how CO2 is able to control fires.

A.VERIFIED ANSWERfact-checked by tutors

Soln:

CO₂ is a non-combustible gas and extinguishes fire in two ways:

(i) It is heavier than oxygen and covers the fire like a blanket and cuts off the contact between oxygen and fuel.

(ii) In cylinders, CO₂ is kept in the liquid form. When released, it expands enormously. This brings down the temperature of the fuel, which helps in controlling the fire.
