Question

Which of the following fuels would produce minimum environmental pollution?
1. Hydrogen
2. Diesel
3. Kerosene
4. Coal

Answer 1

Correct Answer - Option 1 : Hydrogen

The correct answer is Hydrogen.

• Hydrogen fuels would produce minimum environmental pollution.
  • When hydrogen burns it becomes water vapour.
  • There are no carbon or other compounds released into the atmosphere.
  • There are various compounds including carbon dioxide and carbon monoxide released when other fuels are burnt.
  • Hydrogen is the chemical element with the symbol H and atomic number 1.
    • Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all baryonic mass. 
• Hence, option 1 is correct.

• Coal:
  • Coal on burning comes in oxygen, the chemical energy is converted into thermal energy that is heated.
  • It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion.
  • But it also gives carbon dioxide and methane in the environment.
• Diesel:
  • The petroleum fuels burn to give carbon dioxide, water and nitrogen.
  • Diesel is a type of engine that produces enough heat to burn fuel and power a vehicle.
  • combustion of fuel gives these harmful gases which when released into the environment will pollute it.
• Kerosene:
  • It is the combustible hydrocarbon derived from petroleum, a fuel.
  • It is a transparent liquid fuel with a mixture of hydrocarbon chains 6 to 16 carbon atoms in length.
  • so it will also give carbon dioxide and nitrogen to pollute the environment. 

• Carbon Dioxide, carbon monoxide and Methane are harmful to the environment as well as life existing on earth.
  • Their high exposure causes suffocation, dizziness, weakness, loss of coordination.
  • carbon dioxide is the greenhouse gas which leads to increased temperature on the earth.
