CARNOT CYCLE Meaning and
Definition
-
The Carnot Cycle refers to an ideal thermodynamic cycle that consists of four distinct processes and is used as a theoretical basis for the operation of heat engines. Named after the French physicist Sadi Carnot, the cycle illustrates an idealized engine that operates between two heat reservoirs (a hot and a cold reservoir) to maximize its efficiency.
The cycle begins with an isothermal expansion process, during which the working substance (such as a gas) absorbs heat energy from the hot reservoir at a constant temperature while expanding. The gas expansion leads to an increase in volume and work done by the system.
Next, the system undergoes an adiabatic (without heat transfer) expansion, resulting in a decrease in temperature and a further expansion of the gas.
Following the adiabatic expansion, an isothermal compression process occurs, where the working substance is brought into contact with the cold reservoir at a constant temperature and rejects heat energy while being compressed back to its original volume.
Lastly, an adiabatic compression process takes place, in which the temperature rises and the working substance is compressed back to its initial state. This completes the cycle, and the system is ready for another iteration.
The Carnot Cycle serves as a conceptual framework for understanding and evaluating the performance of ideal heat engines, highlighting the importance of reversible processes and thermodynamic efficiency. While real-world engines cannot achieve Carnot's theoretical efficiency due to energy losses, the Carnot Cycle provides valuable insights into the maximum efficiency attainable by any engine operating between given temperature limits.

Etymology of CARNOT CYCLE
The word "Carnot Cycle" is named after Sadi Carnot, a French physicist who is often credited as the father of thermodynamics. Sadi Carnot proposed the concept of the Carnot cycle in his seminal work "Réflexions sur la puissance motrice du feu" ("Reflections on the Motive Power of Fire") published in 1824. The cycle was named after him to honor his significant contributions to the field of thermodynamics.
