Simulation of kinetic theory of molecules.
This is planned to use for H2 class at Hiroo Gakuen.

You can see an adiabatic transition by changing a mass of the piston.
An above chart shows a relation between the displacement of the piston and time.
A below one is about the average speed of particles which is equivalent to the temperature.

increase the mass...
->temperature goes up
->the piston displaces downard

decrease the mass...
->temperature goes down
->the piston displaces upward
