Q2/(A): What are the various types of open system ? BA particular substance undergoes a mechanically reversible process expanding from an initial state of 20 bar to a final state of 8 bar. The path for the process is described by the equation: 0.036 , Where P is in bar and v is in m. if AU for the P= change of state is ( - 1400 I), Determine W, Q and AH?

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?
