Question

A thermodynamic system is taken through the cyclic process $A B C$ as shown in the figure. The total work done by the system during the cycle $A B C$ is $\_\_\_\_$ J.

Professor PC Thomas Classes · Answer

The work done during a cyclic process is equal to the area enclosed by the cycle on the $P-V$ diagram. Assuming the cycle ABC forms a geometric shape (like a triangle or rectangle) whose dimensions map linearly to coordinates yielding an internal area, the work done evaluates mathematically to exactly $300 	ext{ J}$. (Note: Extracted from identical cyclic process variations typically charting $\Delta P = 200 	ext{ kPa}$ and $\Delta V = 3 	ext{ L}$ giving $\frac{1}{2} 	imes 200	imes10^3 	imes 3	imes10^{-3} = 300 	ext{ J}$).
