Question

(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 are 55 kJ/g and 80°C, respectively. These values for fuel B are 80 kJ/g and 10°C, respectively. On burning, the fuel A produces CO2 and H2O while the fuel B produces CO2 , CO and SO2. Give three points of relative advantages and disadvantages of these two fuels.
