Question

6. In an experiment 5 kg of a fuel has completely.
burnt. The heat produced was measured to be
180000 KJ. Calculate the calorific value of the
fuel​

Answer 1

Answer:

Total mass of fuel = 4.5 kg

Total heat produced = 180,000 kJ

Heat produced by burning 1 kg of fuel = 180,000 kJ/4.5 kg = 40,000 kJ/kg.

So, calorific value of fuel = 40,000 kJ/kg.
