Two identical containers with identical particle types and numbers are
placed back to back and separated by a moveable barrier as shown in the animation. Initially the barrier is in static equilibrium. P = Pressure, T =Temperature, N = # of molecules, V = Volume. Assume changes occur slow enough so that there is no adiabatic heating or cooling. To "Set T left" ot "Set N right" pause the animation, change the value, click set, then click play.
