Question

In an experiment, 4.5 kg of a fuel was completely burnt. The heat produced was measured to be 180,000 kJ. Calculate the calorific value of the fuel.​

Answer 1

Answer:

Mass of fuel = 4.5 kg

Heat produced = 180000 kJ

Calorific value of fuel = amount of energy produced per kg of fuel

                                   = $\frac{180000}{4.5}$

                                   = 40000 kJ/kg

Answer 2

Answer:

40,000kj/kg

Explanation:

Total mass of fuel=4.5kg total heat produced

=180,000kj heat produced by burning 1k of fuel=180,000kj/4.5kg=40,000kj/kg.

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