Answer 2

Hey friend,

Here's your answer :

Since water is denser than petrol therefore it sinks down thereby allowing the petrol to rise up to the surface and continue to burn.

Moreover, the existing temperature is so high that the water poured on the fire evaporates even before it would extinguish the fire.

Hope this helps!!!
