can anyone answer it quick? please

|A two-phase liquid-vapor mixture of refrigerant R-134a at 200 kPa with a quality of 0.25 is contained in a pistoncylinder device as shown in the fig. The refrigerant is heated at constant pressure until the piston hits the stops. At this point its specific volume is 0.07771 m 3 /kg. Then heat transfer continues at constant volume until the pressure doubles. NOTE: If interpolation is needed you can take the closest value in the table instead but let me know. Use 5 decimal digits when using specific volume. a.) Plot the process in a P-v-diagram with respect to saturations lines. b.) Fill de table below c.) Determine the total mass if the initial volume is 1.11 m3 T(C) (m 3 /kg) (kJ/kg) phase 1 2 3 a
