Description

The use of the Dewar flask in the experiment P2.3.1.1 essentially prevents the loss of heat to the surroundings. This vessel has a double wall; the intermediate space is evacuated and the interior surface is mirrored. The water is stirred thoroughly to ensure a complete exchange of heat. This experiment measures the mixing temperature ϑm for different values for ϑ1, ϑ2, m1 and m2.
