Which one of the following is the best condition for performing maximum work by any thermodynamic system?
Correct answer: D. Isothermal condition
- A. Adiabatic condition
- B. Isobaric condition
- C. Isochoric condition
- D. Isothermal condition
Explanation
The isothermal condition is the best for performing maximum work, particularly in reversible processes, because the system can exchange heat with the surroundings while maintaining a constant temperature. This allows for efficient energy transfer and work performance. In contrast, adiabatic processes involve no heat exchange, which limits the work potential; isobaric processes maintain constant pressure, which does not necessarily maximize work; and isochoric processes do no work since the volume does not change.

About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.
