The workdone can also be calculated by:
Correct answer: C. Area of the curve under the P-V graph
- A. Gradient of the tangent of the curve of P-V graph
- B. Gradient of the tangent of the curve of P-T graph
- C. Area of the curve under the P-V graph
- D. Area of the curve under the P-T graph
Explanation
To calculate the work done on the object, we must calculate the area under the curve of a P-V graph.

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.
