Answer 1

According to the question In an experiment on burning 2kg of candle 10000 kj of energy was produced, and we have to determine its calorific value.

•The calorific value of fuel is the amount of heat produced by the complete combustion of 1 kg of fuel.

Heat produced by 2 kg of fuel =10000 kJ.

Heat produced by 1 kg fuel = 10000/2 KJ/Kg =5000 kJ/kg.

So, the calorific value of the fuel is 5000 kJ/kg.
