A rigid tank is divided into two equal parts by a partition. One part of the tank contains 8.4 kg of compressed liquid at 400 kPa and 65 degrees Celsius while the other part is evacuated. The partition is now removed, and the water expands to fill the entire tank. Determine the entropy change of water during this process if the final pressure in the tank is 30 kPa.
