An ice cube at \(0\text{ }^\circ\text{C}\) is placed into a thermally insulated container filled with warm water at \(30\text{ }^\circ\text{C}\). The container and its contents are completely isolated from the surroundings. After some time, the ice cube melts completely and the system reaches thermal equilibrium at \(15\text{ }^\circ\text{C}\). Which of the following correctly identifies the sign of the entropy change of the warm water, \(\Delta S_{\text{water}}\), and the sign of the total entropy change of the combined ice-water system, \(\Delta S_{\text{total}}\)?
