Question

how does carbon dioxide extinguish a fire?​

Answer 1

Answer:

Carbon dioxide extinguishes work by displacing oxygen, or taking away the oxygen element of the fire triangle. The carbon dioxide is also very cold as it comes out of the extinguisher, so it cools the fuel as well.

Answer 2

Explanation:

Carbon dioxide is heavier than air, as a result it settles beneath of major constituents of air and forms a blanket on the fire and cuts down the supply of oxygen, so, in the absence of sufficient oxygen the fire gets extinguished.
