Shown in the following fi gure is a process from which Species A is isothermally compressed from 0.5 bar and 300 K to 1 bar. The insets of each state, which are of equal volume, contain a

“molecular view” of species A.

Next consider the open system shown in the following fi gure. Species A fl ows steadily through the system and expands through the valve from an inlet state at 5 bar and 300 K to an exit state at 1 bar.
You may assume Species A acts as an ideal gas. In analogy to the closed system depicted earlier, the equal volume insets are shown in this fi gure. Fill in the corresponding “molecular views” of Species A. Explain your answer.
