PhET Simulation of Gas Behavior
Description: This pHet JAVA based Simulation program shows a collection of molecules bouncing around in a chamber closed by a piston. The volume, temperature, and number of moles can be changed independently, and pressure is calculated. The program also shows gas mixing and effusion.
