Description

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.

Learning objectives

• Equation of adiabatic change of state
• Polytropic equation
• Rüchardt’s experiment
• Thermal capacity of gases
