01.01 Velocity of molecules and the MAXWELL BOLTZMANN distribution function What you can learn about Kinetic theory of gases Temperature Model kinetic energy Average velocity Velocity distribution
Principle and tasks By means of the model apparatus for kinetic theory of gases, the motion of gas molecules is simulated and the velocity is determined by registration of the throw distance of the glass balls. This velocity distribution is compared to the theoretical MAXWELL-BOLTZMANN equation.
