Question

In an experiment, 5.0 kg of a fuel was completely burnt. The heat produced was measured to be 150000kJ. The calorific value of the fuel is: *
3000 KJ/kg
45000 KJ/kg
75000 KJ/kg
30000 KJ/kg
​

Answer 1

Answer:

Calculate the calorific value of the fuel. 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.
