1.	Hydrogen compounds are abundantly available on earth, and it has high calorific value. But this is not used as a common fuel. Give any two reasons. What are the processes that are being developed to use hydrogen as a common fuel ?
Answer» Solution :Hydrogen is not used as a COMMON fuel because : (i) When hydrogen is lighted, it burns with an explosion. (ii) It is very DIFFICULT to STORE and transport hydrogen. Hydrogen as a fuel : Fuel cells are being developed that can store energy produced by BURNING hydrogen. Development of some MATERIALS that can absorb hydrogen and then release it at a steady rate.
