Let there be a closed enclosure of 1 m3 volume and adiabatic walls, separated by a movable wall also adiabatic. Enclosure 1 has a temperature of 800 K and enclosure 2 has a temperature of 400 K. Both enclosures contain 20 moles of a biatomic gas and are initially in mechanical equilibrium with each other. A reversible thermal machine comes in contact with both enclosures, as shown in the drawing, and begins to produce work. Determine: ei M a) Final temperature of the two enclosures. b) Maximum work obtained. c) Final pressure and volume of each enclosure, as well as the entropy increment of each enclosure
