1.	The calorific values of three fuels A, B and C are 33 kJ/g, 48 kJ/g and 150 kJ/g, respectively. A is solid, B is liquid and C is a gas at room temperature. On combusion, both A and B produce 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 si the most ideal ? Give two reasons to support your answer.
Answer» Answer :Fuel B is the most IDEAL fuel; (i) Leaves no residue on burning (II) High calorific VALUE of 48 kJ/g(iii) Does not BURN explosively
