Sourav was heating oil to fry potato chips. The cooking oil all of a sudden caught fire. He took water to pour on the fire to extinguish it. But meanwhile his mother came and switched off the gas and covered the wok completely with a plate.Do you think pouring water to the burning oil would have worked? Why?b. Do you think what Sourav’s mother had done is right? Why? Why isn’t hydrogen gas used as a domestic or industrial fuel, although it has a very high calorific value? Give reason.
plz tell

Answer:
No. Because water is not suitable for fires involving oil.
Sourav should have switched off the flame of the stove and put a plate on the frying pan. By doing this the contact between oil and oxygen is completely cut off and the flame will put out after a few seconds.
Note: Burning Requires Oxygen.
