Here is the answer :)
The calorific value of a substance is a measure of its heating power, which depends on the composition of the substance being burned.
For example,
when one gram of wood is burnt completely it produces 17 kilojoules heat. Therefore, the calorific value of wood is 17 KJ/g. in similar manner, when 1 gm of kerosene oil is burnt completely it produces 48 kilojoules heat. So, the calorific value of kerosene oil is 48 KJ/g.
