Question

How do water and carbon dioxide gas help in extinguishing fire?

Answer 1

Answer:

hi

Explanation:

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:

Water is one of the most common fire extinguishing agents used. It works by removing heat and oxygen from the fire triangle. It reduces the temperature of combustible substance below its ignition temperature. Water vapours surround the combustible material. This results in cutting off air supply causing the fire to extinguish.

Carbon dioxide gas is a nonflammable and is gas heavier than oxygen. It, therefore, covers the fire like a blanket. This results in cutting off the contact between the combustible substance and oxygen. As a result, fire gets extinguished.
