In an experiment, 4.5 kg of a fuel was completely burnt. The heat produced was measured to be 180,000 kJ. Calculate the calorific value of the fuel.

Class 8th NCERT - Science 6. Combustion and Flame

Answer :

The calorific value of the fuel is the amount of heat produced by the complete combustion of 1 kg of fuel.

Now,

Heat produced by 4.5 kg of fuel is given to be = 180000 kJ

Therefore, heat produced by 1Kg of fuel = 180,000 kJ/4.5 Kg = 40,000 kJ

Hence, the calorific value of the fuel is 40,000 kJ/kg.
