Ideal Gas with Maxwell's Demon

Ideal Gas with Maxwells Demon is a handy, easy to use, Java based simulation tool designed to display a two-dimensional ideal gas in a square box, monitored by Maxwells Demon (which allows only faster than average particles to move from the right side to the left side, while allowing only slower than average particles to move the other way).
In the model, the particles are initially spread throughout the box with random positions and random velocities (with a Maxwell distribution of speeds). One window shows an animation of the motion of the particles in the box, while another window plots the temperature of the gas on each side of the box as a function of time. The user can turn the Demon on/off, or reverse the velocities of all particles.System requirementsJava
