Work done in an isobaric process is given by _.
Correct answer: B. PdV
- A. PdT
- B. PdV
- C. VdP
- D. P2Dv
Explanation
In an isobaric process, the pressure remains constant while the volume changes. The work done by or on the system in this process is given by the formula: W = PdV volume change where P is the constant pressure and dV = (Vf - Vi) is the change in volume.Therefore, the correct answer is (B) PdV.

About Thermodynamics
Thermal equilibrium and heat explain how temperature and energy transfer are related, while molar specific heats describe the heat required by a gas at constant volume or constant pressure. The first law connects heat supplied, work done and change in internal energy, with sign conventions kept distinct from temperature changes.
