Description

In experiment C2.3.1.1, coal is burned and the heat of combustion is determined with a calorimeter. The calorimeter completely surrounds the sides and top of the combustion chamber. The hot combustion gases generated are fed through a double glass coil and give off their energy to the environment (the glass element and the bath liquid) in the form of heat. In this way, the heat of combustion can be determined using the total heat capacity of the calorimeter.
