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:

A) 0.015 kJ/kg

B) 60,000 kJ/kg

C) 15 kJ/kg

D) 150 kJ/kg

Answer 1

The calorific value of the fuel, given that 2.5 kg of it produces 1,50,000 kJ of heat, is found to be 60,000 kJ/kg. The correct answer is B) 60,000 kJ/kg.

Step-by-step explanation:

The question pertains to calculating the calorific value of a fuel given the heat produced by the complete combustion of a known mass of the fuel. The calorific value represents the amount of energy released when a certain mass of fuel is fully combusted.

To find the calorific value, we can use the formula:

Calorific Value = Amount of heat produced / Mass of fuel combusted

In this case, the amount of heat produced is 1,50,000 kJ, and the mass of the fuel is 2.5 kg. Therefore, the calorific value would be:

Calorific Value = 1,50,000 kJ / 2.5 kg = 60,000 kJ/kg

So, the correct answer is: B) 60,000 kJ/kg
