Question

Why is CNG considered a cleaner gas?

Answer 1

Hint: CNG refers to Compressed Natural Gas. It is considered to be a new form of fuel used in automobiles which is cheaper and causes less pollution. Petrol, diesel, wood, CNG are some forms of fuel that are used commercially.

Complete answer: CNG or Compressed Natural Gas is considered to be a cleaner gas because it causes less pollution as compared to other fuels like petrol or diesel. It exhausts a lesser amount of nitrogen dioxide, carbon dioxide, and sulphur dioxide while burning as compared to other fuels. It also produces less amount of carbon monoxide. It is quite cheaper than other fuels like petrol or diesel. CNG is prepared from dead organic matter which makes it eco-friendly or environmentally friendly. When this Compressed Natural Gas exhausts, hydrogen gas is burnt and energy is released. The end product or the product which is left behind is water which does not cause any pollution. It costs less than other fuels and safer than those fuels. As it produces water as its end product, no air pollution is caused which saves people from lung cancer, different respiratory diseases and skin diseases or rashes. Compressed Natural Gas is used commercially as fuel for automobiles, heating purposes, generating electricity.

Note: The petrol, diesel, wood, CNG are some forms of fuel which are used commercially. While petrol and diesel cause respiratory problems and air pollution, wood-burning leaves residue in the air causing air pollution and straining of eyes, reddening of the eyes. On comparing with these fuels, CNG is not only cost-effective but also safer to use, pollution-free, and causes no diseases.
