Question

"A fuel has calorific value of $25,000kJ/kg$."
What does the above statement represent?

• A. $4kg$ of fuel will release $1,00,000kJ$ energy on combustion.
• B. $1kg$ of fuel will release $1,00,000kJ$ energy on combustion.
• C. $1kg$ of fuel will take $25,000kJ$ energy on combustion.
• D. $4kg$ of fuel will take $1,00,000kJ$ energy on combustion.

Answer 1

The correct option is A $4kg$ of fuel will release $1,00,000kJ$ energy on combustion.

Calorific value is the amount of heat energy produced on complete combustion of $1kg$ of fuel.

Hence, $1kg$ of fuel gives $25,000kJ$ of energy.
$4kg$ of fuel will give $1,00,000kJ$ of energy.
