Explain the construction of a calorimeter. Draw the necessary figure.
A device used for heat measurement is called a calorimeter.
Construction of a Calorimeter
It consists of a metallic vessel and stirrers. They are made of copper or aluminium.
The vessel is then kept inside a wooden jacket which contains heat-insulating materials.
The outer wooden jacket acts as a heat shield, and reduces the heat loss from the inner vessel.
The outer jacket has an opening through which a mercury thermometer is inserted into the calorimeter.
