Principle

A mass oscillates on a volume of gas in a precision glass tube. The oscillations maintained by leading escaping gas back into the system. The adiabatic coefficient of various gases is determined from the periodic time of the oscillation.

Benefits


Suitable for many different gases

Compact, easily transportable setup


Tasks

Determine the adiabatic coefficient of air nitrogen and carbon dioxide (and also of argon, if available) from the periodic time of the oscillation T of the mass m on the volume V of gas.
