Dulong–Petit law

Layer 1 — Physicsin the statistical-mechanics subtree

Classical limit for the molar heat capacity of monatomic crystalline solids: C_V = 3R ≈ 24.94 J K⁻¹ mol⁻¹, independent of the element. Follows from equipartition applied to 3N harmonic oscillators with kinetic + potential energy (½ k_B T…
