Entropy may also refer to:
Thermodynamics and statistical mechanics
- Entropy (classical thermodynamics), thermodynamic entropy in macroscopic terms, with less emphasis on the statistical explanation
- Entropic force. The product of temperature and the gradient of the entropy density is viewed an effective force, yielding a gradient in the energy density of a system.
- Entropy production. Development of entropy in a thermodynamic system.
- Entropy (statistical thermodynamics), the statistical explanation of thermodynamic entropy based on probability theory
- Configuration entropy, the entropy change due to a change in the knowledge of the position of particles, rather than their momentum
- Conformational entropy, the entropy change due to a change in the "configuration" of a particle (e.g. a right-handed vs. a left-handed polyatomic molecule)
- Tsallis entropy, a generalization of Boltzmann-Gibbs entropy
- von Neumann entropy, entropy in quantum statistical physics and quantum information science
