Question

30000 kJ of heat energy is released by 3 kg of a fuel? What is the calorific value of the fuel?
Select an answer
A 10000 kJ
B 107 3/kg
c 10000 kJ/kg
D both (B) & (C)​

Answer 1

Answer:

(c)

Explanation:

Calorific value can be calculated using this relation:

3kg --> 30000kJ

1kg --> ?kJ

this implies

(1*30000)/3 = 10000kJ

Since the question asks for calorific value the units must be kJ/kg

10000 kJ/kg (Final Answer)
