Read the instructions and then go to the links at the bottom of this page to activate various kinds of experiments that can be done with this applet.
This applet is designed to simulate the diffusion process which occurs when gases of different temperatures are mixed. To activate the mixing click one time on the red vertical bar that separates the two chambers. After a few moments, the bar will turn green and the gases will start to mix and share their energy. The counters in the respective chambers indicate the number of particles in that chamber. The thermometers will start to change temperature as the mixing process is occurring. Eventually both chambers will reach the same temperature.
In order for this simulation to properly run - its important that the user not be doing other activities on the machine as this will interfere with the timing aspects of the experiment.
Different initial conditions are setup in a series of experiments and questions related to that experiment can be found underneath the apparatus.
