FAQs on Important Questions : Hydrogen - Class 11

1. What is hydrogen and its importance?
Ans. Hydrogen is a chemical element with the symbol H and atomic number 1. It is the lightest and most abundant element in the universe. It is important for a wide range of applications, including fuel, chemical production, and energy storage. Hydrogen fuel cells also have the potential to revolutionize the transportation industry by providing a clean and efficient energy source for vehicles.
2. How is hydrogen produced?
Ans. Hydrogen can be produced through several methods, including steam methane reforming, electrolysis, and biomass gasification. Steam methane reforming is the most common method of producing hydrogen, where hydrogen is extracted from methane by reacting it with steam. Electrolysis involves splitting water molecules into hydrogen and oxygen using an electrical current, while biomass gasification converts organic materials into hydrogen gas.
3. What are the advantages of using hydrogen as a fuel?
Ans. Hydrogen is a clean-burning fuel that produces only water vapor when it is burned, making it a low-emission and environmentally friendly alternative to fossil fuels. It is also highly versatile and can be used in a wide range of applications, including transportation, heating, and power generation. Additionally, hydrogen is abundant and can be produced from a variety of sources, including water, natural gas, and biomass.
4. What are the challenges associated with using hydrogen as a fuel?
Ans. One of the main challenges associated with using hydrogen as a fuel is its storage and transportation. Hydrogen is a highly flammable gas and must be stored and transported safely to avoid accidents. Additionally, the production of hydrogen can be energy-intensive, and the cost of producing and distributing hydrogen fuel can be high. As a result, the development of a hydrogen fuel infrastructure is a major barrier to widespread adoption.
5. What is the future of hydrogen as a fuel?
Ans. Hydrogen has the potential to become a major fuel source in the future, especially as the world seeks to move towards cleaner and more sustainable energy sources. Advances in technology and the development of a hydrogen fuel infrastructure are likely to make hydrogen more accessible and cost-effective in the coming years. Additionally, the use of hydrogen in fuel cells has the potential to revolutionize the transportation industry by providing a clean and efficient energy source for vehicles.
