Question

In an experiment 5Kg of fuel was completely burnt. The heat produced was measured to be

2,00,000 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.

Answer 2

Answer:

40000 kJ/kg

Step-by-step explanation:

Since, calorific value is the the amount of heat energy produced on complete combustion of 1 kg of a fuel

So, Amount of Heat Produced/Amount of fuel= Calorific Value

=2,00,000 kJ/5Kg

=40000 kJ/kg
