2. A container is divided along its length L by a frictionless movable partition into two sections. The container is insulated to prevent any exchange of heat to or from the outside. Initially the partition is held a distance ro from the left side. The left side of the partition contains m moles of ideal gas and the right side contains na moles of ideal gas. Both sides are at the same temperature but have different Pressures. When the partition is released it moves until the system reaches equilibrium. (a) The partition moves from ro to a new position r. Compute the change of entropy, AS, of the system.In the diagrams, all light bulbs are identical and all emf devices are identical. In which circuit (I, II, III, IV, V) will the bulbs be dimmest? III IV V O Il O IV OV
