A rigid tank contains 5 kg of water initially at 275C and 3000 kPa, then the water is cooled while being stirred until its pressure drops to 1630 kPa. (a) Determine the phase and properties (specific volume and entropy) of water at the initial state (state 1). (4 Marks)s Superheated vapor, 0.07591 m /kg, 6.4153 kJ/kg K (b) Determine the phase and properties (specific volume and entropy) of water at the final state (state 2). (4 Marks) Saturated liquid-vapor mixture, 0.07591 m/kg, 4.86 kJ/kg K (c) Determine the entropy change of the water during this process. (2 Marks) -7.78 kJ/K
