The work done 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
The work done (W) in a thermodynamic process can indeedbe calculated by finding the area under the P-V graph (pressure-Volume diagram).That's because work done is defined as: W = PV Graphically, this integral represent the area under the curve in a P-V diagram. So, the area under the P-V graph gives you the work done by the system 9or on the system, depending on the context).

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.
