Answer 2

Explanation:

The Calorific value of value is the amount of heat released during the reaction.This released heat is known as heat of combustion.

The calorific value of cooking gas is 48 KJ/kg.So,we used fuel A.

The calorific value of alcohol is 30 KJ/kg.So,we used fuel E.

The calorific value of wood is 17 KJ/kg.So,we used fuel B.

The calorific value of Hydrogen is 150 KJ/kg.So,we used fuel C.

The calorific value of Kerosene is 50 KJ/kg.So,we used fuel D.
