Maxwellian velocity distribution
Principle
By means of the model apparatus for kinetic theory of gases the motion of gas molecules is simulated and the velocities determined by registration of the throw distance of the glass balls. This velocity distribution is compared to the theoretical Maxwell- Boltzmann equation.
Benefits
- For both demonstration and student experiments
- Unique experiment to quantitatively study kinetic gas theory
- With detailed experiment guide
