a) As shown in Figure A2-a, a piston-cylinder assembly with two set of stops contains a mass of 3 kg of saturated liquid-vapor mixture at a pressure of 1.65 bar. At state 1, 1 kg of the water is in a liquid phase and the remaining water is in a vapor phase. The piston sitting on the stops starts to move when the pressure inside the cylinder reaches 5 bar due to heat transfer. The heat transfer stops when the total volume increases by 20%. H₂O m=3 kg Figure A2-a (1) Determine the initial and final temperatures. Determine the mass of liquid when the piston begins to move. Devermine work done during this process and show the process on a P-v diagram. (H) (iii)
