Explain the construction of a calorimeter. Draw the necessary figure.

Steps to follow for the construction of calorimeter are as follows.

● Calorimeter consists of an inner vessel and outer vessel. No heat transfer between these vessels.

● The inner vessel is made up of copper.

● A thermometer (for measuring temperature) and a stirrer (for stirring liquid) are attached to the inner vessel.

● Water is kept in calorimeter such that inner vessel and water have the same temperature.

● The hot substance is kept at water such that water, calorimeter, and hot substance will be at the same temperature.

● Works on the principle that heat lost by hot substance must be equal to heat energy gained by water and calorimeter.

A figure of calorimeter is given below.
