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

Given :

Weight of fuel burnt = 4.5kg

To find :

Calorific value = ?

Formula used :

Calorific value =

$\frac{amount \: \: of \: \: \:heat \: \: \:produced}{weight \: \: of \ \: \: fuel \: \: \: burnt}$

Solution :

Calorific value =

$\frac{180000}{4.5}$

∴ Calorific value = 40,000 kJ/kg
