Question

Out of the following which is able to control fires?

A.NH3(Amonia)

B.H2(Hydogen)

C.CO2(Carbon dioxide)

D.Cl2(Chlorine) ​

Answer 1

Answer:

answer is option c (co2)

Explanation:

CO₂ is a non-combustible gas and it is also non-supporter of combustion. It extinguishes fire in two ways:

1. Since it is heavier than oxygen, it covers the fire like a blanket and cuts off the contact between oxygen and fuel.

2. 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.
