Question

When 1.5Kg of methane gas was burnt, the amount of heat energy liberated was measured to be 75000KJ. Caculate the calorific value of methane gas.​

Answer 1

Answer:

30,000 kJ/kg

Explanation:

The calorific value of fuel(Methane gas, in this problem) is the amount of heat produced by the complete combustion of 1 kg of fuel.

Heat produced by 1.5 kg of fuel =75000 kJ.

Heat produced by 1 kg fuel =  $\frac{75000}{1.5}$

​= 30,000 kJ/kg

Hence, the calorific value of the Methane gas is 30,000 kJ/kg.
