½ kg of a liquid-vapor water mixture in a rigid tank initially at 2 bar is heated by 120V heater for 5 minutes until it becomes a saturated vapor at 4 bar. Changes in kinetic and potential energies can be ignored. Determine:
a) The volume of the
b) The initial quality of the mixture
c) The change in internal energy
d) The current of the heater assuming all of the power consumed by the heater is transferred as heat to the mixture
