How this entity was disambiguated
This entity first appeared as the object of triple T5538006 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Gibbs dividing surface Context triple: [Tolman length, relatedTo, Gibbs dividing surface]
-
A.
Tolman length in thermodynamics of curved interfaces
The Tolman length in thermodynamics of curved interfaces is a theoretical parameter that quantifies how the surface tension of a fluid interface depends on its curvature, especially for small droplets and bubbles.
-
B.
Gibbs phase rule
The Gibbs phase rule is a fundamental thermodynamic principle that relates the number of components and phases in a system to its degrees of freedom, determining how many variables can be independently varied without changing the number of phases in equilibrium.
-
C.
Boltzmann–Gibbs entropy in statistical mechanics
Boltzmann–Gibbs entropy in statistical mechanics is the standard measure of disorder or uncertainty in a system, quantifying how many microscopic configurations correspond to a given macroscopic state and forming the basis of classical equilibrium statistical mechanics.
-
D.
Gibbs paradox
The Gibbs paradox is a concept in thermodynamics and statistical mechanics highlighting an apparent contradiction in the entropy change when mixing identical versus distinct gases, which helped clarify the role of particle indistinguishability.
-
E.
Gibbs ensemble
The Gibbs ensemble is a statistical physics framework that describes the probabilistic distribution of microstates for systems in thermal equilibrium, typically at fixed temperature, volume, and particle number.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
