Reversibility of basic thermodynamic processes: evaluate the statement Statement: “The constant-pressure, constant-volume, and general p·vⁿ processes are regarded as irreversible processes.” Decide whether this statement is correct.

Concept/Approach

• A process type (isobaric, isochoric, polytropic p·vⁿ) can be carried out reversibly or irreversibly depending on how it is executed (quasi-static with negligible gradients vs. finite gradients, friction, etc.).
• Thus, none of these process labels inherently implies irreversibility.

Final AnswerDisagree — the statement is incorrect.
