**Piston Cylinder Cyclic Motion:** A piston cylinder performs a cyclic motion (1 -> 2 -> 1) with 2 process paths as shown below. **Question (5):** Is the moving boundary work for process B (\(W_{b,B}\)) positive or negative? _________ **Graph Explanation:** - The graph is a Pressure (P) vs. Volume (V) diagram. - It illustrates two paths for the process from state 1 to state 2 and back to state 1. - Path A indicates the trajectory from point 1 to point 2. - Path B indicates the trajectory from point 2 back to point 1. - The cycle is represented by a closed loop on the graph with arrows indicating the directions of paths A and B. **Options for Answer:** - A. Positive - B. Negative
