Instruction
Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Target entity: Joule–Thomson effect
Context triple: [Linde process, uses, Joule–Thomson effect]
  • 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.
NED2 Entity disambiguation (via description) gpt-5-mini-2025-08-07
Target entity: Joule–Thomson effect
Target entity description: The Joule–Thomson effect is a thermodynamic phenomenon in which a real gas changes temperature during expansion at constant enthalpy, a principle crucial to gas liquefaction and refrigeration processes.
