Why a heat engine can never achieve one hundred percent efficiency
In short: Explore the fundamental limits of thermodynamics through a clear breakdown of the Carnot cycle. This video explains the mechanics of heat engines and the essential difference between reversible and irreversible processes.
The video examines the four distinct steps of the Carnot cycle, detailing how pressure, volume, and temperature fluctuate during each stage. By using PV diagrams, it illustrates how engine efficiency is determined solely by the temperatures of the hot and cold reservoirs.
Beyond theory, the presentation includes an example problem to demonstrate how to calculate efficiency and manage variables like pressure and volume.
