1.	Basic principle of hydrogen economy is transportation and storage of energy in the form of liquid or gaseous hydrogen . Which property of hydrogen may be useful for this purpose ? Suppose your answer with the chemical equation if required.
Answer» Solution :Hydrogen is a gas at room temperature . Because of its BULK, it is DIFFICULT to transport it either by rail or by road. However, by cooling and applying high pressure , gaseous `H_(2)` can be converted into liquid `H_(2)` which has much smaller volume and HENCE can be transporated EASILY. Thus, the baseic property of hydrogen which is useful for hydrogen economy is that if can be converted into a liquid by cooling under high pressure.
