Q3) Explain how the use of CNG in automobiles has reduced pollution in our cities.

Solution :

Compressed Natural Gas(CNG) is a clean fuel and does not give smoke when burnt as compared to other petroleum containing fuels like petrol and diesel.

For automobiles to run, petroleum fuel is burnt.

The combustion of fuel leaves unburnt carbon particles in the air, along with carbon monoxide(CO) - poisonous and harmful gas.

Breathing CO causes headache,dizziness,etc.

CNG burns completely leaving no harmful residue.

Hence, the use of CNG in automobiles has reduced pollution in our cities.
