Question

Q1. Choose the correct option.
i. Which of the following fuels causes least smoke ?
a) Petrol
b) CNG
c) Diesel
d) Kerosene​

Answer 1

(C) CNG fuel causes less smoke.

Explanation:

• Natural gas is less damaging to the environment than coal. It is made up of methane and emits fewer greenhouse gases. It also burns cleaner and leaves no residue. Furthermore, natural gas emits almost little particulate matter, one of the most dangerous pollutants in the atmosphere.
• Natural gas is also easier to transport than other types of coal since it can be stored and transferred via pipelines, tiny storage units, and other means.
• CNG is also regarded as the cleanest-burning fuel available today. Because of its reduced carbon content, CNG burns cleaner than petroleum-based goods. It emits the fewest pollutants of any other fuel and creates far fewer emissions than gasoline. Compared to petroleum fuels, CNG emits 20-30% fewer greenhouse gases and 95 percent lower exhaust emissions.
