P2.3.3.2 Converting Mechanical Energy into Heat Energy - Recording and Evaluating with CASSY

Converting Mechanical Energy into Heat Energy - Recording and Evaluating with CASSY These experiments P2.3.3.1 und P2.3.3.2 show the equivalence of mechanical and heat energy. A hand crank is used to turn various calorimeter vessels on their own axes, and friction on a nylon belt causes them to become warmer. The friction force is equivalent to the weight G of a suspended weight. For n turns of the calorimeter, the mechanical work is thus This results in an increase in the temperature of the calorimeter which corresponds to the specific heat capacity To confirm the relationship the two quantities are plotted together in a diagram. In the experiment P2.3.3.1, the measurement is conducted and evaluated manually point by point. The experiment P2.3.3.2 takes advantage of the computer-assisted measuring system CASSY.
