A thermodynamic process (B \(\rightarrow\) E) was completed as shown below. The work done is equal to area under the limits.
Show Hint
The work done in a thermodynamic process is given by the area under the P-V curve. Always analyze the curve to ensure the area is enclosed correctly for the process.
Step 1: In a thermodynamic process, the work done is represented by the area under the curve on the P-V diagram. From the given graph, the path \( B \rightarrow C \rightarrow D \rightarrow E \) correctly represents the work done in the system as the area under this curve.
Step 2: The other paths do not enclose the area under the curve in the correct manner to represent the work done during this thermodynamic process. Therefore, the correct path for the work done is \( B \rightarrow C \rightarrow D \rightarrow E \). Thus, the correct answer is option (3).
