net change in entropy of a system in a carnot's cycle is
Answers
Answer:
Net change in entropy of a system in a carnot's cycle is zero .
Explanation:
An ideal closed thermodynamic cycle with reversibility is known as a Carnot cycle. Isothermal expansion, adiabatic expansion, isothermal compression, and adiabatic compression are the four sequential processes that take place.
Each cycle results in a net entropy increase that is negative and proportional to the entropy produced within the system. Therefore, there is no net change in entropy across a cycle. Entropy is a characteristic of a physical system, hence this is the case. Entropy is a function of thermodynamic state and remains constant during all cyclic processes.
- Entropy change is a characteristic of the system
- Entropy in the start and final states would be the same since it is a state function.
- The heat interactions and irreversibilities during the cycle may cause entropy to be produced. But the system is reset to its default state.
Because of this, entropy change in a cycle is zero, regardless of its kind or nature (reversible or irreversible).
