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.
Fuel B is the most ideal fuel due to the following main reasons:
(i) As it leaves no reside on burning like the other two.

(ii) As an idle fuel it has a high calorific value of 48 KJ/g.

(iii) Moreover it does not burn explosively.
