Question

in an experiment 4.5 kg fuel was completely burnt, the heat produced was measured to be 90000 KJ, calculate the calorific value of 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.
