Which of the following process provides us maximum work done by system?
Correct answer: D. Isobaric
- A. Isothermal
- B. Adiabatic
- C. Isochoric
- D. Isobaric
Explanation
The correct answer is D, 'Isobaric'. In an isobaric process, the pressure remains constant, and the work done by the system involves a change in volume, which is calculated as the product of pressure and volume change. This yields the maximum work for the processes listed, as the system can expand or contract fully under constant pressure. The other processes either involve no work (Isochoric), have work limited by constant temperature or no heat exchange (Isothermal and Adiabatic), or do not maximize work output under the conditions given.

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.
