Q75 · Chemistry
Which of the following p-V curve represents maximum work done ?
The figure, described in words
Options are p-V graphs labelled Isothermal: (1) steep curve over a small volume range with area shaded to V axis, (2) closed elliptical cycle, (3) curve over a wide volume range enclosing large area under it, (4) vertical line (no volume change).
