Question 4: A system consisting of 1kg H0 undergoes the below processes: Process 1-2: Constant volume heating from P = 500 kPa, T =160 C to 1MPa Process 2-3: Constant pressure process to saturated vapor Process 3-4: Constant volume cooling a) Is this a closed-system or open-system? (5p.) b) Calculate the work from processes 1 to 3. First, determine (fix) each of the states by filling the below table (7p. each, total: 21p), and then calculate the work (2p each, total: 6p). State 1 State 2 State 3 Given property values to Thermodynamic State table used fix the state
