Most of the fuels contain carbon as one of the constituents. Name a fuel which has very high calorific value but does not contain carbon.
Hydrogen is the fuel which has a very high calorific value and do not contain any carbon)
The calorific values of three fuels A, B and C are 33 KJ/g, 150 KJ/g, respectively. A is solid, B is liquid and C is a gas at room temperature. On combustion, both A and B produces carbon dioxide while C explodes forming steam. B and C leave no residue after combustion while A leaves behind some solid residue. Which one of the three fuels is the most ideal? Give two reasons to support your answer.
