A rigid tank is divided into two equal sections by a diaphragm. Initially, one of the sections has a pressure of 0.3 MPa and 1500 g of water at 333 K. The other part is empty (vacuum). When the diaphragm ruptures, the entire tank is filled with water and the pressure becomes 0.015 MPa. Calculate the change in entropy of water.
