Solution
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.
