DIFFUSION


 

Molecules in Container:

Temperature

Diffusion: Thermal motion and directed fields.
In this simulation a total of 2000 molecules are set free in the center of a container and their motion is observed in time.

 START, initiates the process.
 freeze, freezes action. 
 resume, resumes the simulation.
mark, labels one of the molecules.

The container can be removed (remove container), allowing the free escape of the molecules to infinite space. The number of molecules left in the area where the container was is shown in Molecules in container. Container may be resored with restore container.
 
A hole can be opened in the container to allow the escape through a restricted area (open channel) which then can be subsequently closed (close channel).

A force field  can be applied at any time (Impose a Field) and subsequently removed (remove field).

Temperature may be modified (between 2 and 100 C) by typing a value in the temperature field.
