18. Incomplete combustion of fuels does not contribute
18. Incomplete combustion of fuels does not contribute
The correct option is C global warming
Explanation for correct option:
Option (C):
- Incomplete combustion of fuels occurs in an oxygen deficit environment.
- An example of incomplete combustion would be burning coal, during which large quantities of soot and Carbon monoxide are released.
- Global Warming is an increase in global temperatures which occurs due to increased concentrations of greenhouse gases in the atmosphere, mainly from human activities such as burning fossil fuels, and farming.
Explanation for incorrect options:
Option (A): Photochemical smog is a mixture of pollutants that are formed when nitrogen oxides and volatile organic compounds (VOCs) react to sunlight, creating a brown haze.
Option (B): The gases like Nitrogen dioxide and Sulphur dioxide that are released from factories, burning of fossil fuels, etc. dissolve in rainwater and form corresponding acids. This rain when reaches in earth's surface is called acid rain.
Therefore, incomplete combustion of fuels releases carbon monoxide, nitric oxide NO, etc., leading to photochemical smogs and acid rain but not global warming.
Hence the correct answer is (C).
