The area enclosed by the curve ABDCA for a Carnot heat engine represents the work done by Carnot engine
Correct answer: D. during one cycle
- A. at any instant
- B. averagely
- C. during its operation
- D. during one cycle
Explanation
The enclosed area in a PV diagram for a thermodynamic cycle represents the net work done by the system during one cycle. In the case of a Carnot cycle, this enclosed area indeed represents the work done by the engine in one cycle

About Work
Work is done when a force produces displacement, with its value determined by the component of force along the displacement. The topic covers positive, negative and zero work, work by variable forces from force-displacement graphs, and the connection between net work and change in kinetic energy.
