Description

In the two experiments P5.5.2.1 and P5.5.2.2, a cylindrical electric oven with a burnished brass cylinder is used as a “black body”. The brass cylinder is heated in the oven to the desired temperature between 300 and 750 K. A thermocouple is used to measure the temperature. A water-coolable screen is positioned in front of the oven to ensure that the setup essentially measures only the temperature of the burnished brass cylinder. The measurement is conducted using a Moll’s thermopile; its output voltage provides a relative measure of the radiated power M. The thermopile can be connected via the µV Sensor S / Box, either to Mobile-CASSY or to the CASSY computer interface device. In the former case, the measurement must by carried out manually, point by point; the latter configuration enables computer-assisted measuring and evaluation. The aim of the evaluation is to confirm Stefan-Boltzmann’s law.
