please mark me as brainliest....
Explanation:
1. Water cools and smothers the fire at the same time. It cools it so much that it can't burn anymore, and it smothers it so that it can't make any more of the oxygen in the air explode. You can also put out a fire by smothering it with dirt, sand, or any other covering that cuts the fire off from its oxygen source.
2. 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
