The equation W = P(V₂-V₁) represents work done by a gas in:
Correct answer: C. Isobaric
- A. Free expansion
- B. An isothermal expansion
- C. Isobaric
- D. An expansion at constant temperature
Explanation
The formula W = PΔV = P(V₂-V₁) calculates work done under the condition that pressure (P) is constant throughout the process. A process that occurs at constant pressure is called an isobaric process.

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.
