Question

Discuss the impact of burning fuels on air.

Answer 1

Carbon fuels like wood, coal, petroleum release unburnt carbon particles. These fine particles are dangerous pollutants, which cause respiratory diseases such as asthma.
Incomplete combustion of these fuels gives carbon monoxide gas, which is a very poisonous gas.
Combustion of most fuels releases carbon dioxide in the environment. Increased concentration of carbon dioxide in the air causes global warming.
Use of fossil fuels damages the environment with the realease of toxic gases like oxides of nitrogen and sulphur. Such gases are responsible for acid rain, which, in turn, is very harmful for crops, buildings and soil. Moreover, nitric oxide and CFCs are also responsible for depletion of ozone layer.
