Question

How does dumping water on fire extinguishes it?

• A. Water cools the burning fuel below the ignition point
• B. Water cuts the supply of oxygen
• C. Water cuts the supply of oxygen and water cools the burning fuel below the ignition point
• D. Water supports fire

Answer 1

The correct option is A

Water cools the burning fuel below the ignition point

The reason water extinguishes a flame is because it is exceptional at absorbing heat. Water takes up a lot of energy to increase its temperature and to transform into steam, so dumping a large quantity of water on a fire will decrease temperature down to a level where the flame would not be able to propagate.
