Question

collect information about the type of fuels used for cooking in your area .discuss with your/teacher/parents/others which fuels are less polluting and why

Answer 1

fuels such as liquid petroleum gas (LPG) lignite and coal. LPG is less polluting because it burns quickly and burns completely rather than coal which burns partially producing harmful gases that pollute the air

Answer 2

Various types of fuels are used for cooking like LPG, coal, wood, kerosene, and petroleum gas.

EXPLANATION:

The least polluting fuel is LGP or Liquefied Petroleum Gas. LPG burns quickly and completely as compared to other fuels like coal and wood.

Fuels like wood, coal and kerosene do not burn completely and have high content of carbon. These when burnt result in a lot of pollution and thus are not preferred as cooking fuels.
