Step 1: Identify the adiabatic process and its parameters.
The question asks for the work done at the stage where the system does not interact by heat with its surroundings. This describes an adiabatic process. In the given P-V diagram (Figure 2), the curve from point 1 to point 2 represents the adiabatic process, as indicated by the arrows and the typical shape of an adiabatic curve.

From the graph, we can identify the initial and final states for the adiabatic process (1 to 2):
Initial state (Point 1):
Volume $V_1 = 0.05 \text{ m}^3$.
Pressure $P_1 = 1 \times 10^5 \text{ N/m}^2$. (The label on the
