Problem
Consider the following three-step procedure carried out at 1 atm:
1. Ice at 0 °C melts completely in a rigid, sealed container held at the same temperature.
2. The resulting liquid water is transferred to an open beaker and rapidly boiled until half the mass is lost as vapor.
3. The remaining liquid is returned to the original sealed container and cooled slowly to 0 °C until ice and water coexist.
For each numbered step, indicate whether the process is reversible or irreversible under the stated conditions and briefly justify your classification.
