Fire Extinguishers
1.water extinguishes fire because as it evaporates,the vapours surround the burning substance,cutting off the oxygen supply,thus inhibiting burning process
2.hot water will extinguish fire more quickly than cold water as hot water will evaporate faster
3.in case of electrical or oil(petrol) fires,water cannot be used as extinguisher.
because water is a conductor and helps to keep conduct current and Encourage fire.
and it is heavier than oil so thus,oil floats over it and continues to burn.

sooooo use carbon dioxide(co2),silicon dioxide (sand) as a extinguisher
