A fixed-mass system contains water (H20) in a rigid (fixed-volume) container. The mass of the water is mass, m= 1.805719781 kgs. A process occurs having the following initial and final thermodynamic properties.

Initial Pressure: P1 = 1000kPa Initial Temperature: T1 = 600 ^oC Final Temperature: T2 = 140 ^oC

Determine the following: (Neglect changes in kinetic and potential energy)

1. 1W2 (work done on.by the system, in kJoules)

2. 1Q2 (heat transfer to/from the system, in kJoules)

3. (S₂ - S₁)sys (Entropy change of the system, in kJ/K)

4. What is the maximum temperature of the surroundings (I.e., T₀ in degrees K) for which there is no 2nd Law violation? (Hint: consider the net entropy change, system plus surroundings.)
