Question

Explain how ${\mathrm{CO}}_2$ is able to control fire

Answer 1

${\mathbf{CO}}_{\mathbf{2}}$ acts as a fire extinguisher:-

• We all that for combustion we need oxygen.
• When there is any fire, the Carbon dioxide used on that fire does not directly react with it to extinguish the fire.
• As Carbon dioxide is heavier than water, it cuts the connection between oxygen and the fuel by covering the fire.
• The Carbon dioxide is kept under pressure, and when it is released it expands and cools down.
• This cool down that is the decrease in the temperature also helps to control the fire and put it out.
