Ideal Gas PVT Measurement

This applet allows you to measure the pressure-volume-temperature (PVT) relationship for an ideal gas. Observe the atom motions in one panel; notice that the particles do not interact with one another. In the other panel observe averages for the pressure at different settings for the temperature and density. If you change the settings for the simulation (number of molecules and/or temperature), you can reset the simulation averages by pressing the corresponding button in the Averages panel.

The simulated system is surrounded by hard walls. Momentum transfer between the disks and the walls is used to measure the system pressure.

Adjustment of the particle number halts the simulation. Press the "Continue" button to restart.
