Question

How water and CO2 is helpful in controlling fire​

Answer 1

$\huge\fbox\colorbox{lime}{❥Answer♡}$

Carbon dioxide is non-combustible gas and it can be used to extinguish fire by flooding the area around the fire with the gas. ... 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

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.
