Energy can be transmitted through heat convection, heat radiation or heat conduction. The greater the thermal conductivity of a wall, the higher the temperature of its exterior. This property is used to compare the temperatures and thus the thermal conductivity of aluminum and glass with each other by means of the thermal generator.

In order to compare an aluminum beaker with a glass beaker, hot water is poured into an aluminum beaker. In addition, hot water is available in another glass beaker. The temperatures at the bottom of these beakers are compared with each other by means of a thermal generator. The higher the displayed voltage, the higher the temperature.

The solar ray collector is illuminated with a halogen lamp of known light intensity. The heat energy absorbed by the collector can be calculated from the volume flow and the difference in the water temperatures at the inlet and outlet of the absorber, if the inlet temperature stays almost constant by releasing energy to a reservoir.
