Chapter 8—GASES, liquids, and solids.
Add or remove atoms inside the balloon. Watch what happens to the barrier as the pressure tries to equalize.
Boyle's Law Simulation. See what happens to the pressure when the volume is increase/decreased.
Charles's Law Simulation. Watch what happens to the volume as the temperature is changed.
Increase the temperature slider to see the solid melt, then vaporize! To simulate the behavior of polar molecules, change the van der Waals slider to Strong. For non-polar, leave it at weak.
