Thermodynamics question?

Initially a rigid tank equipped with a resistance heater contains 5kg of saturated liquid water at

150 kPa. The heater is turned on for a period of time until 50% of the water by mass is vaporized.

Assume that the tank is insulated and determine the entropy change of the water through this

process in kJ/W. Sketch the process on a T-s diagram with respect to the dome and a line of

constant pressure.
