Question

Any chemistry Expert?

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

Answer 1

Hello dear!❤️

Total mass of fuel - 4.5kg

Total heat produced - 180,000kJ

Heat produced by burning 1kg of fuel :

$\frac{18000kj}{4.5kg}$

40,000kJ/kg

So, calorific value of fuel= 40,000kJ/kg

Hope this helps
