Solve the same problem, assuming the process is isobaric, i.e. that the pressure in both vessels is the same, and the partition moves freely, maintaining a constant pressure during heat exchange. 18.20 The two halves of the vessel contain one mole of gas, and T2 > T1. The walls of the vessel are adiabatic, the partition is absolutely thermally conductive. How will the entropy of the system change during isochoric temperature equalization (i.e., when the partition is motionless)?
