PV Diagrams

add Q at constant:    

Please wait for the animation to completely load.

There is a time delay—since the system must be in equilibrium—before the change of state occurs.

Note:  In this applet, N = nR = NpkB  (so that N is number of moles times the gas constant or the number of particles times the Boltzmann constant).  This, then, means the ideal gas law is PV = NT for this animation.
