A cylinder-piston device contains 20.0 kilograms of a mixture of liquid and saturated vapor with a quality from 0.3725 to 7000 kPa. Then an electrical resistance placed in the cylinder is turned on for 20 minutes until the volume quadruples at constant pressure. The system gains heat equivalent to 500 kJ/kg. (Use 5 digits (0.0012345) and make the P-v diagram, also obtain the other data)

b) Final pressure (kPa)
H2O
c) Boundary work (kJ)
d) Nominal power (kJ/s)
