The+Gas+Chamber

SUMMARY of the APPLET In the gas chamber, you can easily study the relationships between (1) temperature and pressure, and (2) volume and pressure of a gas. The applet shows the changing pressure of gas inside a chamber. If the pressure exceeds 10 atmospheres, the chamber breaks. A graph of the data is also produced while you do the experiments.

HINTS and SUGGESTIONS The directions for the experiments are given at the bottom of the page after it loads. They are fairly easy to follow, but a few points need to be clarified.
 * 1) In experiment one, it is important to follow the instructions very carefully, otheriwise the applet does not work. In fact, sometimes when I load this applet, it simply doesn't work correctly. Re-loading it does not always fix the problem.
 * 2) Before you begin experiment two, lower the temperature to 200 K. If you forget to do this, the experiment might be over before you get to see a good graph. It is interesting to repeat this experiment at very low temperatures, less than 50 K.
 * 3) I have never been successful with the third experimental procedure. I should be a responsible internet user and e-mail the authors with my concerns!

WHO CREATED THIS APPLET The physics department at the University of Oregon has a small group of people, led by Dr. Greg Bothun, who create and publish applets through their website. More information about the authors and more applets can be found [|at this website]. The name of this website is vlab, which probably stands for virtual lab.
