A rigid tank has 2 sections, X and Y, which are separated by a very thin divider, and both contain water. Section X has water at P = 0.20 MPa, with a total V = 1 m3. Section Y is at P = 500 kPa and T = 673.15 K. The divider is removed and heat transfer takesoccurs so that the water comes to a uniform state at T = 373.15 K. How much heat is transferred in the process if initially, section X contains 2 kg and Y contains 3.5 kg of water respectively.
