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 from the periodic time of the oscillation T of the mass m on the volume V of gas.
