I need help with 3A and B. Please show me the detailed steps.
![For a mole of a perfect monoatomic gas, the internal energy, \( U \), can be expressed as a function of the pressure and volume as
\[ U = U(P,V) = \frac{3}{2} PV \]
a) Calculate explicitly the line integral of \( dU \) along the closed path \( ABCD \) shown as a black trace in the \( P - V \) graph below.
**Graph Explanation:**
The graph is a \( P \) (pressure) vs. \( V \) (volume) graph with the following key points:
- Point \( A \) at \((V_1, P_1)\)
- Point \( B \) at \((6V_1, P_1)\)
- Point \( C \) at \((6V_1, 3P_1)\)
- Point \( D \) at \((V_1, 3P_1)\)
The path follows:
- From \( A \) to \( B \): Horizontal line at \( P = P_1 \)
- From \( B \) to \( C \): Vertical line at \( V = 6V_1 \)
- From \( C \) to \( D \): Horizontal line at \( P = 3P_1 \)
- From \( D \) to \( A \): Vertical line at \( V = V_1 \)
b) Compute the following line integrals between the points \( B \) and \( C \) in the figure above:
1. \( \int_h PdV \), along the path, \( h \), described by \( P = 3P_1 V_1 / (V - 3V_1) \), shown in red in the figure above.
2. \( \int_s PdV \), along the path, \( s \), shown in black in the figure above.
Use these results to demonstrate that \( \delta W = -PdV \) is not an exact differential.
