	•	Differences between real gases and ideal gases

Experiment description:_..

Sulphur hexafluoride (SF₆) serves as a real gas and is examined in a measurement cell with only a minimal dead volume. Sulphur hexafluoride is especially suitable for this experiment, as its critical temperature (T_C = 319 K) and its critical pressure (p_C = 37.6 bar) are both relatively low. It is also non-toxic and is quite safe for use in teaching and in practical classes.

Additionally required:_..
