Dulong–Petit law for molar heat capacity of many solids at high temperature

Target entity: Dulong–Petit law for molar heat capacity of many solids at high temperature
Context triple: [equipartition theorem, implies, Dulong–Petit law for molar heat capacity of many solids at high temperature]

• A. Onsager reciprocal relations
  Onsager reciprocal relations are fundamental symmetry relations in nonequilibrium thermodynamics that link pairs of coupled fluxes and forces, showing that certain transport coefficients are equal.
• B. Kirchhoff's law of thermal radiation
  Kirchhoff's law of thermal radiation is a fundamental principle in thermodynamics stating that, for a body in thermal equilibrium, its emissivity equals its absorptivity at each wavelength.
• C. Langevin theory of paramagnetism
  The Langevin theory of paramagnetism is a classical statistical model that explains how the magnetization of paramagnetic materials depends on temperature and applied magnetic field by treating atomic magnetic moments as non-interacting dipoles subject to thermal agitation.
• D. Curie law of magnetization
  The Curie law of magnetization is a fundamental principle in magnetism stating that the magnetic susceptibility of a paramagnetic material is inversely proportional to its absolute temperature.
• E. Sackur–Tetrode equation
  The Sackur–Tetrode equation is a fundamental formula in statistical mechanics that gives the absolute entropy of an ideal monatomic gas in terms of its volume, temperature, and particle number.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Dulong–Petit law for molar heat capacity of many solids at high temperature
Target entity description: The Dulong–Petit law states that many crystalline solids have an approximately constant molar heat capacity of about 3R at sufficiently high temperatures, reflecting classical equipartition of energy among atomic vibrations.
