Question

60 kg of fuel was completely burnt for an experiment. The amount of heat energy was found to be 180000KJ. Calculate calorific value of the fuel.​

Answer 1

3000 kJ/kg

Step-by-step explanation:

The calorific value of a substance is the amount of heat produced per unit mass by the combustion of the substance.

It is given by:

`C=(Q)/(m)`

where

Q is the amount of heat released

m is the mass of the fuel

In this problem, we have:

m = 60 kg is the mass of fuel

`Q=180,000 kJ` is the amount of heat released

Therefore, the calorific value of the fuel is:

`C=(180,000)/(60)=3000 kJ/kg`
