During a class discussion on ‘fuels for household’ Sarita suggested petrol. But her teacher said it is not a safe fuel for household activity and asked her to sit. Sarita wondered why petrol can’t be used as a fuel for household activity though its calorific value is high.

Answer:
Petrol vapourises easily so it can lead to rapid combustion. Hence it is not safe as household fuel. We use LPG, kerosene and wax.
