$\text{Hint: Compression process}$ $\text{Step 1: Analyze the P-V diagram}$ $\text{Looking at the P-V diagram, we can see that the volume is decreasing from } V_i \text{ (initial volume) to } V_f \text{ (final volume).}$ $\text{When volume decreases }(V_f < V_i)\text{, the process is a compression.}$ $\text{The diagram shows a stepped process with decreasing pressure, representing a non-ideal compression path.}$ $\text{Step 2: Determine the work done}$ $\text{The work done in a thermodynamic process can be calculated as the area under the curve in a P-V diagram:}$ $W = \int_{V_i}^{V_f} P \, dV$ $\text{For compression processes, the sign convention in thermodynamics is:}$ $\text{• Work done ON the system is positive}$ $\text{• Work done BY the system is negative}$ $\text{Since } V_f < V_i \text{, we have a compression process where the surroundings do work on the system.}$ $\text{We can also use the simplified formula for work:}$ $W = -P(V_f - V_i)$ $\text{Since } V_f < V_i\text{, the term } (V_f - V_i) \text{ is negative.}$ $\text{With the negative sign in front, the overall work becomes positive.}$ $\text{Step 3: Verify the conclusion}$ $\text{From the P-V diagram, we can visually confirm that work is being done ON the system (compression), which corresponds to positive work.}$ $\text{The area enclosed by the stepped path represents the work done, and in this case of compression, the work is positive.}$ $\text{Therefore, the work done during the process shown in the P-V diagram is positive.}$
