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.

Answers (1)

Total mass of fuel = 4.5 kg
Heat produced by burning the given mass of fuel = 180,000 kJ.
We know that calorific value of fuel
Heat produced in kJ ÷ Total mass burnt
= 180,000 kJ ÷ 4.5 kg = 40,000 kJ/kg

Hence, the calorific value of the given fuel = 40,000 kJ/kg
