3.134 One kilogram of air in a piston-cylinder assembly undergoes two processes in series from an initial state where P - 0.5 MPa, T -227°C: Process 1-2: Constant-temperature expansion until the vol- ume is twice the initial volume. Process 2-3: Constant-volume heating until the pressure is again 0.5 MPa. Sketch the two processes in series on a p-v diagram. Assum- ing ideal gas behavior, determine (a) the pressure at state 2. in MPa, (b) the temperature at state 3, in °C, and for each of the processes (c) the work and heat transfer, each in kJ.

A piston-cylinder assembly contains a mystery substance that undergoes a series of processes. Process 1-->2: Constant pressure process at 5bar from v1=.07m3/kg to v2=.12m3/kg Process 2->3: Constant volume process to saturated vapor Process 3->4: Constant temperature process to quality of 50% Process 4->5: Constant volume process to 5bar Sketch the processes on Pt, Pv, and Tv, plots. Lable the axes including property values; use closed dots to show the states, use solid lines to connect the states, add number and arrows to make clear the states numbers and process directions. Could this be considered a thermodynamic cycle? Why or why not?
Carbon dioxide (molar mass 44 kg/kmol) expands reversibly in a perfectly thermally insulated cylinder from 3.7 bar, 220 0C to a volume of 0.085 m3. If the initial volume occupied was 0.02 m3, calculate the final pressure in bar to 3 decimal places. Assume nitrogen to be a perfect gas and take cv = 0.63 k J / k g K.
b) A piston-cylinder system mounted vertically and has a partition on it. It contains 5 kg of saturated liquid water at 200 kPa. Heated system causes some of the water evaporates and the piston begins to move. When the piston is touching blockers, which was conceived by the volume of water is 1000 liters. Water is heated until the pressure increased four times. Show the process involved in p-v and T-v diagrams.
