What is the main component of CNG, or compressed natural gas, increasingly used as a vehicle fuel?

Explanation

CNG, or compressed natural gas, is composed mainly of methane that has been compressed to less than one percent of its volume at standard atmospheric pressure, making it practical to store and transport in vehicle fuel tanks. It’s promoted as a comparatively cleaner-burning alternative to petrol and diesel, producing fewer particulate emissions. CNG has seen widespread adoption as a transport fuel in various countries as a way to reduce fuel costs and certain emissions. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
