?

Water is not effective in extinguishing a fire caused by petrol because

A) The flame is too hot for water to cool it down B) Water and petrol react chemically C) Water and petrol are miscible with each other
D) Water and petrol are immiscible with each other and petrol which forms the upper layer continues to burn

Answer & Solution

Correct Answer: Option D

As water is heavier than petrol therefore slips down permitting the petrol to rise to the surface and continue to burn. Besides, the existing temperature is so high that the water poured on the fire evaporates even before it can extinguisher the fire. Thus the petrol fire cannot be extinguished by water.
