Question

4. Explain the working of a fire extinguisher with the help of
diagram and give the chemical equation.​

Answer 1

Explanation:

Most fire extinguishers work by separating the fuel from the oxygen. The oxygen comes from the air. It is the same oxygen we breathe. Since the oxygen has to be in contact with the fuel, if you can coat the fuel with something that keeps the oxygen away, the fire will go out.

Answer 2

Answer:

Fire extinguishers work on the principle that oxygen is required for a fire to burn. A fire extinguisher contains Carbon-dioxide which keeps the oxygen away from the fire which extinguishes the fire.
