Which gas is used in fire extinguishers to extinguish the fire?
Carbon dioxide is considered the best fire extinguisher to put off fires caused by the burning of inflammable liquids such as petrol or oil because carbon dioxide is heavier than oxygen and it covers the fire like a blanket. Since the contact between the fuel and oxygen is stopped, the fire is controlled.
Therefore, carbon dioxide is the gas used in fire extinguishers to extinguish the fire.
