Determining the Adiabatic Exponent cp/cV of Various Gases using the Gas Elastic Resonance Apparatus

In the experiment P2.5.3.2, the adiabatic exponent is determined using the gas elastic resonance apparatus. Here, the air column is sealed by a magnetic piston which is excited to forced oscillations by means of an alternating electromagnetic field. The aim of the experiment is to find the characteristic frequency f0 of the system, i.e. the frequency at which the piston oscillates with maximum amplitude. Other gases, such as carbon dioxide and nitrogen, can alternatively be used in this experiment.
