You can get the concept of: Linear thermal expansion, volume expansion, specific heat, lattice potential.
Principle: The increase in liquids and linear expansion of various materials determined as a function of temperature. To investigate the extension tube made of brass, steel, copper, aluminum and glass are clamped in a special device to measure. Water flowing through the tube - sets the specified temperature. The change in length at different temperatures measured using a dilatometer. Measuring changes in the volume of water produced using a flat-bottomed flask with a registered a vertical pipe, which is located in the calorimeter.
