Question

In an experiment, 5 kg of a fuel was completely burnt. The heat produced was measured to be
2,50,000 kJ. Calculate the calorific value of the fuel.
(A) 12,50,000 kJ/kg
(B) 2,55,000 kJ/kg
C) 50,000 kJ/kg
(D) 5,000 kJ/kg
​

Answer 1

Calorific value= Kilojoules/Kilogram

=500,000/5

=100,000

Therefore the calorific value of the fuel is 100,000

Answer 2

Answer:

formula = KJ / KG = 250,000/5

=50,000
