Physics: Thermodynamic entropy definition clarification

Clarifying that the thermodynamic definition of Entropy requires a reversible system.

Physics

Learn about the basic principles that govern the physical world around us. Solid understanding of algebra and a basic understanding of trigonometry necessary.

Laws of thermodynamics

In these videos and articles you'll learn how the first law of thermodynamics relates the change in internal energy of a gas, heat that enters the gas, and work done on the gas. PV diagrams will be discussed, as well as the four common thermal processes: isobaric, isochoric/isovolumetric, isothermal, and adiabatic. You'll also learn about how the second law of thermodynamics relates the entropy change to the multiplicity of microstates and the heat that enters a macroscopic system. The efficiency of a heat engine will also be explained.
