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 andfinal thermodynamic properties.
Initial Pressure: P1 = 1000kPa Ă‚Â Ă‚Â Initial Temperature:T1 = 600 oC Ă‚Â Ă‚Â Final Temperature: T2 = 140oC
Determine the following: (Neglect changes in kinetic andpotential energy)Ă‚Â Ă‚Â
1. 1W2 (work done on.by the system, in kJoules)Ă‚Â Ă‚Â
2. 1Q2Ă‚Â Ă‚Â (heat transfer to/from the system, inkJoules)
3. (S2 - S1)sys (Entropy change of thesystem, in kJ/K)Ă‚Â Ă‚Â
4. What is the maximum temperature of the surroundings (I.e.,T0 in degrees K) for which there is no 2nd Lawviolation? (Hint: consider the net entropy change, system plussurroundings.)
