Question:medium
An ideal gas undergoes a cyclic process ABCA wherein AB is an isothermal expansion, BC is an isochoric pressure drop, and CA is an adiabatic compression. The work done by the gas in the complete cycle is:

Show Hint
Key Exam Tip:
For any closed cycle, $\Delta U = 0$, hence $W = Q$. The net work done is the area enclosed by the P-V diagram, which is usually non-zero.
