__**Gas Laws Applet**__ In this applet, you have three things you can change: the number of molecules, the volume available for them to bounce around in, and the temperature. Like it says at the bottom, the more often the red molecules hit the piston and make a sound, the higher the pressure. It's meant to change pitch also, but that so far hasn't worked for me. Basically, you can see the relationship between volume and pressure, as well as temperature and pressure.

 * What is it:**


 * Hints and suggestions:**


 * 1) Start with no more than five molecules. You really don't want anymore, because the cuckoo clock sound it makes when it hits the piston will drive you insane. Drag the volume all the way down so it has the maximum amount of volume (you do that by dragging the piston down) and lowering the temperature as far as you can. What do you notice about the speed the molecules move at? How often does it hit the piston so you hear the cuckoo clock sound?
 * 2) Whatever you do, do not add more molecules. Now see what happens if you turn up the temperature, first half way, and then all the way up. What changes?
 * Ok, drag the temperature down again, because the cuckoo clock is probably annoying you. Now see what happens if you change the volume by dragging the platform of the piston up (the thing you dragged down first) Now what do you notice? What changes?
