Definition check: what do we call a sequence of processes returning to initial state? A series of operations that occurs in a fixed order and restores the system to its initial state at the end. Choose the correct term.

Difficulty: Easy

reversible cycle
irreversible cycle
thermodynamic cycle
none of these

Correct Answer: thermodynamic cycle

Explanation:

Concept
A thermodynamic cycle is any sequence of processes that starts and ends at the same thermodynamic state. A cycle may be idealized as reversible or consist of real (irreversible) processes; the definition itself is the closed path on a property diagram.

Final Answer
thermodynamic cycle
