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 and disadvantages of these two fuels.
Arrange the following fuels in the order of decreasing calorific values (keeping the fuel with highest calorific value first):
Biogas, Kerosene, Wood, Petrol, Hydrogen gas, Methane
