Answer» (a) What is a fuel? Give five examples of fuels. (b) What are the characteristics of an ideal fuel (or good fuel) ? (c) The calorific value and ignition temperature of fuel A re 55 kj/g and $80^{\circ} C,$ respectively. These values for fuel B are 80 kj/g and $10^{\circ} C,$ respectively. On burning, the fuel A produces $C O_{2} a n d H_{2} O$ while the fuel B produces $C O_{2}, C O a n d S O_{2}$ . Give three points of relative advantages and disadvantages of these two fuels.
