Work done in a quasi-static process equals area under curve in:
Select the correct option:
Solution
Incorrect! Answer:
P-V diagram
Thermodynamic work done by a gas during expansion or compression is given by: W=∫PdV
- On a P-V (Pressure-Volume) diagram, this integral represents the area under the curve between the initial and final volumes.
- For a cyclic process, the net work done is the area enclosed within the cycle loop.
