Question
A well-insulated rigid tank contains 3.5 kg of a saturated liquid-vapor mixture of water at 200 kPa. Initially, three-quarters of the mass
is in the liquid phase. An electric resistance heater placed in the tank is now turned on and kept on until all the liquid in the tank is
vaporized. Determine the entropy change of the steam during this process. Use steam tables.
H₂O
200 kPa
We
The entropy change of the steam during this process is
kJ/K.
