In the given figure, four different processes for a constant amount of an ideal gas, all starting at state a, are shown.In which of the given processes, the system does ZERO work on its surrounding?
Correct answer: A. A
- A. A
- B. B
- C. C
- D. D
Explanation
The correct answer is Option A. In a thermodynamic process, the system does zero work on its surroundings if there is no change in volume. This is known as an isochoric process. Since option A represents a process where the volume remains constant, the system does zero work. In contrast, Options B, C, and D all involve a change in volume, which means that work is done by the system on the surroundings.

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.
