Question

"The heat produced by the complete combustion of 2.5 kg of a fuel is 1,50,000 kJ. The calorific value of the fuel is _____________."

You are given four options to choose from:

a) 60,000 Kg/KJ
b) 60,000 KJ/Kg
c) 6,000 KJ/Kg
d) 3,75,000 KJ/Kg

Please select the correct option.

Answer 1

The calorific value of the fuel is 60,000 kJ/kg, which is calculated by dividing the total heat produced by the mass of the fuel burned.

Step-by-step explanation:

The calorific value of a fuel is defined as the amount of heat produced by the complete combustion of a unit mass of fuel. To calculate the calorific value, we use the formula:

Calorific Value = Total Heat Produced / Mass of Fuel Burned

Given that the complete combustion of 2.5 kg of fuel produces 150,000 kJ of heat, we can calculate the calorific value as:

Calorific Value = 150,000 kJ / 2.5 kg = 60,000 kJ/kg

Therefore, the correct option is:

b) 60,000 KJ/Kg
