Hydrogen could well be a fuel for the future. Which of the following statement is true about the potential use of hydrogen as a fuel?

  • A. Easily liquefiable
  • B. Produces lots of green house gases on combustion
  • C. Explosive when mixed with air
  • D. All of the above

Step-by-step solution

Hydrogen is highly flammable and forms explosive mixtures with air over a wide concentration range, making statement C true. Statement A is false because hydrogen has a very low boiling point and is not easily liquefied. Statement B is false because hydrogen combustion produces water vapor, not greenhouse gases.
