Which statement best describes the relationship between the work associated with a quasistatic process for an ideal gas and its representation on a pressure–volume (PV) diagram?
(a) For any quasistatic process, the work done by the gas equals the product of the final pressure and the change in volume, W=PfΔV.
(b) The magnitude of the work done by the gas equals the area bounded by the process curve, the volume axis, and the initial and final volumes.
(c) The work done by the gas equals the change in internal energy of the gas, W=ΔU.
(d) The magnitude of the work done on the gas equals the area bounded by the process curve, the pressure axis, and the initial and final pressures.
