Reversible processes can occur spontaneously
Study Notes
Second Law of Thermodynamics
- Excludes the possibility of constructing 100% efficient heat engines and perpetual-motion machines, violating the Kelvin-Planck statement and the Clausius statement.
- Introduces the concepts of reversible processes, which can be reversed to their initial state, and irreversibilities, which cannot.
- Determines the theoretical performance limits of engineering systems, providing a framework for evaluating their efficiency and potential.
Learn about the principles of the second law of thermodynamics, its applications, and limitations. Understand reversible and irreversible processes, and their implications on engineering systems.
