Explain how CO₂ is able to control fires.

Explain

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

Since it is heavier than oxygen, it covers the fire like a blanket and cuts off the contact between oxygen and fuel.
In cylinders, CO₂ is kept in the liquid form. When released, it expands enormously and cools down. This brings down the temperature of the fuel, which helps in controlling the fire.
