2. 10% An insulated rigid tank is divided into two equal parts by a partition. Initially, one part contains 5 kg of air at 400 kPa and 45 C, and the other part is evacuated. The partition is now removed, and the air expands into the entire tank. Determine (a) the volume of the tank, (b) the final temperature and pressure in the tank, and (c) the total entropy change during this process. 287k7 2. 10% An insulated rigid tank is divided into two equal parts by a partition.
