The training laboratory bench NTC-22.05.12 “Measurement of heat capacity of bodies” is designed for the study of the process of heating materials and measurement of their heat capacity.
The unit consists of the heating module and the control module.
The heating module is a metal housing in which a cylindrical volumetric heater with a tapered bore for mounting the metal test sample is placed. The temperature of metal is measured by a thermocouple mounted in the heater. The heater with a tapered bore for the sample is isolated from the body and the environment. For the experiment the heating module is connected to the control module.
The control module is connected to a PC (not included in the delivery set) via USB-port. In the process of operation the power consumption and amount of heat used for heating the sample are displayed on the PC screen.
The experiment is divided into two stages. At the 1st stage heating and cooling of the empty heater are conducted. At the 2nd stage the sample is placed in the heating module, after which it is heated to a predetermined temperature. By the difference between the amounts of heat spent at two stages heat capacity of the metal is calculated.
The laboratory unit is equipped with a computer-animated model that fully reflects the stages of work, which facilitates the perception of the physical processes and complements the visibility of the experiment. The model can be used for the preparation for laboratory work and for theoretical illustration when studying the specific heat of metals.
