1.	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.
Answer» Answer :FUEL Y is a better fuel ; (i) MODERATE ignition temperature of `75^(@)C` (ii) Produces no harmful gas(LIKE CO) N BURNING.
