Question

List the hazards caused by burning of fuels

Answer 1

Fossil fuels include common sources of energy such as coal and natural gas. These fuel sources developed thousands--sometimes millions--of years ago, depending upon the type. The energy output varies with the material, with peat producing the least amount of energy and the lowest amount of carbon. The pollution resulting from fossil fuels is caused by the toxic emissions they release. Fossil fuel combustion releases carbon dioxide, nitrogen oxide, methane and other emissions in the air. Although some of these chemicals are naturally occurring, the high concentrations cause pollution and its effects.

Answer 2

1) The burning of fuels like wood,coal and petroleum products releases unburnt carbon particles in the air:These fine carbon particles are dangerous pollutants which can cause respiratory diseases.

2)Incomplete combustion of fuels produces a very poisonous gas called carbon monoxide:Excessive inhaling of carbon dioxide gas can kill a person.We should never sleep in a room with closed door and windows,and having a coal fire burning inside.This is because when coal burns in an insufficient supply of air in the room,then a lot of carbon monoxide is produced.when the person sleeping in this room breathe in poisonous carbon monoxide gas,they may all dies.

3)Burning of fuels releases carbon dioxide in air in the environment:Increased percentage of carbon dioxide in air is causing global warming.Carbon dioxide gas in the air trap sun’s heat rays by producing green house effect.
