∙ Water prevent the spreading of fire by lowering down the temperature of a substance. On pouring a large quantity of water on a fire, water will absorb a lot of heat and transform into steam. These steam cut off the oxygen supply. ∙ Thus, water extinguishes fire by lowering the temperature below ignition and removing the oxygen supply.
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 the heat of the fire on water surrounds the burning material and helps in cutting off the supply of air.
