Question

The calorific values of petrol and CNG are 45000 kJ/kg and 50,000 kJ/kg, respectively. If you have a vehicle that can run on petrol as well as CNG, which fuel will you prefer keeping in mind that it should not impact the environment in a negative way?

Answer 1

I prefer CNG over petrol because CNG is a clean fuel and it produces very few harmful gases. This will reduce the air pollution that happens due to the burning of fuel. The calorific value of CNG is higher than that of petrol hence it can be economical.
