The change in entropy is zero for
Correct answer: A. reversible isothermal processes
- A. reversible isothermal processes
- B. reversible adiabatic processes
- C. reversible processes during which no work is done
- D. reversible isobaric processes
Explanation
During a reversible isothermal process, where the temperature remains constant, and the process is carried out reversibly, the change in entropy is zero as there is not temperature chage

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.
