Apiston-cylinder system contains of 3 kg of saturated mixture of water at 160 kpa. initially, water is in liquid phase. heat is now transferred to the water and the piston, which is at the stop, start moving when the pressure reaches 500 kpa. heat transfer continues until the total volume increases by %20. determine, a. the initial and final temperature, b. the mass of liquid when the piston first starts moving, and c. the work done during this proce
