Question

Why are fires produced by burning
oil not extinguished by pouring waters
how is this fire extinguished​

Answer 1

Answer:

Water is heavier than oil. So when it is poured on an oil fire, it sinks to the bottom where it evaporates due to heat of the fire and thus expands rapidly due to which it may push and splatter fire in all directions.Water has more density than oil so oil floats on water hence if we pour water on fire caused by oils it will not extinguish it will promote the fire .

Answer 2

Answer:

Water should not be used to putoff fire when burning of petrol because water contains oxygen and oxygen will make the fire more and more continous and brighter and it will be difficult to putoff the fire.

For fires involving electrical equipment and inflammable materials like petrol, carbon dioxide (CO2) is the best extinguisher. CO2, being heavier than oxygen, covers the fire like a blanket. Since the contact between the fuel and oxygen is cut off, the fire is controlled.
