One kilogram of water contained in a sealed piston-cylinder assembly, initially at 160°C and 200 kPa, undergoes an isothermal compression process to saturated liquid. For this process, the work input required is 471.5 kJ. Determine the following for this process:
(a) the heat transfer (kJ).
(b) the change in entropy (kJ/K).
(c) Draw a T-s diagram for the process.
