Q.17 Single Choice
On complete combustion of 2.4 kg of fuel 'F' 3,60,000
kJ of heat energy is produced. The calorific value of
fuel 'F' is
A
50,000 kJ/kg
B
1,25,000 kJ/kg
C
1,50,000 kJ/kg
D
40,000 kJ/kg​

Answer 1

C ) 1,50,000 kJ/kg

Calorific value is the amount of energy released or produced when 1 kg of fuel burns.

Given that on complete combustion of 2.4 kg of fuel  3,60,000  kJ of heat energy is produced

That is, 360000 kJ of heat for 2.4 kg

It's calorific value will be = 360000/2.4 = 150000 kJ/kg
