- 4.7: Entropy - Physics LibreTextsThe second law of thermodynamics is best expressed in terms of a change in the thermodynamic variable known as entropy, which is represented by the symbol S. Entropy, like internal energy, is a state function.
- Entropy | Definition & Equation | BritannicaEntropy, the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. Because work is obtained from ordered molecular motion, entropy is also a measure of the molecular disorder, or randomness, of a system.
- What Is Entropy? Definition and Examples - Science Notes and ...Entropy is a measure of the randomness or disorder of a system. Its symbol is the capital letter S. Typical units are joules per kelvin (J/K). Change in entropy can have a positive (more disordered) or negative (less disordered) value. In the natural world, entropy tends to increase.
