(1) An insulated piston-cylinder device contains 5 L of saturated liquid water at a constant pressure of 150 KPa. An electrical resistance heater inside the piston is turned on now and electrical work done on steam is 2200 W. Find: (a) initial and final temperature of water (T1 and T2), (b) the work done during this process (W1-2), (c) the entropy change of water and show if the process is possible or not, and (d) plot P-V and T- s diagrams.
