Question

Name any harmful product released by the burning of fuels.

Answer 1

Fuels like wood, petroleum releases unburnt carbon particles which causes respiratory diseases like asthma.

Incomplete combustion of fuels like coal and wood gives off carbon monoxide which is a very poisonous gas.

Burning of diesel and coal produces a suffocating and corrosive gas-Sulphur dioxide gas, and Petrol engines give off gaseous oxides of nitrogen.Oxides of these sulphur and nitrogen dissolves in rain water and causes Acid Rain.
