Question

explain how CO2 is able to control fires​

Answer 1

Answer:

Carbon dioxide covers the fire and cut-off the contact of oxygen and fuel. This is because carbon dioxide is heavier than the oxygen... When carbon dioxide is released, it expands enormously and cools down. Due to this temperature it brings down and this helps in controlling the fire.

Answer 2

Carbon dioxide covers the fire and cut-off the contact of oxygen and fuel. This is because carbon dioxide is heavier than the oxygen. ... When carbon dioxide is released, it expands enormously and cools down. Due to this temperature it brings down and this helps in controlling the fire.

Explanation:

CO

2

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, CO

2

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.
