How does pouring water extinguished a fire.
Answers
Answer:
Water extinguishes heat by cooling down the burning substance. When water is thrown on substances, it gets cooled below its ignition temperature and also stops burning. The water vapour produced by the action of heat of fire on water surround the burning material and help in cutting off the supply of air.
Water extinguishes fire
Explanation:
A fire can be extinguished by removing the fuel, cutting off the oxygen, removing the heat or interfering in the chemical reaction. When you pour water on the fire, water will be converted to steam. Conversion of water to steam requires a lot of energy, which it will steal from the burning material. So it will be cooled down. The resultant steam will displace the air above the fire, so oxygen will be cut off. Thus the fire will be extinguished.
