Principle

The heat of reaction generated during the complete combustion of 1000 g of solid or liquid fuel is known as the calorific value H. In the case of complete combustion of nutritional fats, the gross calorific value can also be determined. In order to ensure complete combustion, the reaction takes place under oxygen. The heat generated during the combustion of a specific amount of fuel is absorbed by a glass jacket calorimeter of known heat capacity. The calorific value of the test substance can be calculated from the temperature increase in the calorimeter.

Tasks

Determine the calorific value of heating oil and the gross calorific value of olive oil.
