प्रश्न
With the help of a neat diagram, explain the working of a calorimeter.
उत्तर
-
A calorimeter is a device used to measure the amount of heat gained or lost by a substance.
-
It consists of a vessel made up of metals like copper or aluminum which are good conductors of heat and electricity.
-
The metallic vessel is kept in an insulating jacket to prevent heat loss to the environment.
Calorimeter -
There are two holes in it. Through one hole a thermometer is inserted to measure the temperature Of the Contents.
-
A stirrer is inserted through another hole for stirring the content in the vessel.
-
The vessel is filled with liquid which is heated by passing a current through the heating element.
-
Using this device we can measure the heat capacity of the liquid in the container.
