Question

In an experiment,6 kg of fuel undergoes complete combustion to produce 480,200KJ of heat. Choose the correct calorific value of fuel.

Answer 1

Answer:

The calorific value of fuel is $80,033\ \frac{KJ}{Kg}$ ·

Explanation:

The calorific value of fuel is defined as "the amount of heat produced by the complete combustion of a unit mass of the fuel"·

Given that,

The amount of fuel undergoes complete combustion $=$ $6\ Kg$

The amount of heat produced during the combustion $=$ $4,80,200\ KJ$

Therefore,

$6\ Kg$ of fuel produced $4,80,200\ KJ$ of heat during the complete combustion reaction·

Then,

$1\ Kg$ of fuel produces $\frac{4,80,200\ KJ}{6\ Kg}$ of heat during the reaction·

That is,

 ⇒  $80,033\ \frac{KJ}{Kg}$ of heat·

Hence,

The calorific value of fuel is $80,033\ \frac{KJ}{Kg}$ ·
