'The ignition temperature of a fuel is 80^(@)C . What does this mean ?

(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 CO_(2) and H_(2)O while the fuel B produces CO_(2), CO and SO_(2) . Give three points of relative advantages and disadvantages of these two fuels.

The calorific value and ignition temperature of fuel A are 55 kJ/g and 20^(@)C respectively. These values for another fuel B are 50 kJ/g and 80^(@)C respectively. Which of the two will be more ideal fuel if, on burning, the fuel A produces CO_(2),SO_(2) and SO_(3) as by-products while the fuel B produces CO_(2) and H_(2)O ? Give two reasons in support of your answer.

Calorific value and ignition temperature of fuel X are 75 kJ/g and 20^(@)C respectively. These values for fuel Y are 50 kJ/g and 75^(@)C respectively. On burning, the fuel Y produces only CO_(2) while fuel X produces CO_(2) and CO. Which of the two is a better fuel ? Give two reasons to support your answer.
