The following description of a supplemental simulation for this article was left out of the print version of AJP, and the online version contains the following graphic and a link to this full description.
The Confined Lennard-Jones System is an idealized statistical mechanics model that simulates a two-dimensional system of particles confined to a box with a constant temperature thermal reservoir at one end and a movable piston at the other. Particles interact through pairwise Lennard-Jones forces and hard-wall contact forces and Newton’s equations of motion are integrated using a Velocity Verlet ODE solver. The main window shows the system with slow-moving particles color-coded as blue and fast particles color-coded as yellow.

The model displays the evolution of the total energy E, the kinetic energy K, the pressure P, and the volume V in a second window. A third window displays histograms and mean values of...
