2. Containers A and B in the diagram each contain different ideal gases at equilibrium. Container holds its volume fixed, while container has a movable piston with a fixed weight. The walls of each container (and the piston) are insulated against heat transfer, and between the chambers is an insulating barrier that is removable. If it is removed, there is another barrier that doesn't allow the gases to mix, but allows very slow heat transfer between the containers (so that the gases in each chamber change states quasi-statically while the heat transfers between them). Container A holds 3 moles of helium, while container B holds 4 moles of molecular (diatomic) nitrogen, and with the insulating barrier in place, both systems are at equilibrium. When the barrier is removed, the piston slowly begins to sink, and comes to rest when the two containers enclose the same volume. insulating barrier A piston B a.

The oxygen is carried through the following processes: (i) Heated at constant pressure from the initial state (state 1) to state 2, which has T = 450 K. (ii) Cooled at constant volume to 250 K (state 3). (iii) Compressed at constant temperature to a volume of 4.00 L (state 4).

A rigid, well-insulated tank contains air. A partition in the tank separates 12 ft^3 of air at 14.7 lbf/in2, 40◦F (left side of the tank) from 10 ft^3 of air at 50 lbf/in2, 200◦F(right side of the tank), as illustrated in the figure.
