How this entity was disambiguated
This entity first appeared as the object of triple T22557195 — 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.

-
A.
Clausius–Clapeyron relation
The Clausius–Clapeyron relation is a fundamental thermodynamic equation that describes how the pressure and temperature of a phase transition, such as boiling or condensation, are related.
-
B.
Trouton’s rule
Trouton’s rule is an empirical thermodynamic relationship stating that many non-associated liquids have nearly constant molar entropy of vaporization at their normal boiling points.
-
C.
Szilard–Chalmers effect
The Szilard–Chalmers effect is a nuclear chemistry phenomenon in which atoms that undergo neutron capture and become radioactive are chemically separated from their original, non-activated atoms due to recoil-induced disruption of their chemical bonds.
-
D.
Krafft point
The Krafft point is the characteristic temperature above which ionic surfactants become sufficiently soluble in water to form micelles, marking a sharp change in their solution behavior.
-
E.
Studies on the expansion of gases
"Studies on the Expansion of Gases" is a foundational 19th-century scientific work by Gustav Magnus that significantly advanced the understanding of gas behavior and thermodynamics.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
