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

$Calorific \;Value = \frac{Heat \;Produced (in \;kJ)}{ Mass \;of\; Fuel (in \;kg)}$

=$\frac{180,000 k\;J}{4.5 \;kg}$

=$\frac{1800000}{45}$

= $\frac{40000 \;kJ}{kg}$
