Question

Match List-I with List-II. List-I: (A) Heat capacity of a body, (B) Specific heat capacity, (C) Latent heat, (D) Thermal conductivity. List-II: (I) J kg⁻¹, (II) J K⁻¹, (III) J kg⁻¹ K⁻¹, (IV) J m⁻¹ K⁻¹ s⁻¹. Choose the correct match.

G1 Physics · Accepted Answer

Heat capacity is C = Q/ΔT, so its unit is J K⁻¹ ⇒ A–II. Specific heat capacity is s = Q/(mΔT), so its unit is J kg⁻¹ K⁻¹ ⇒ B–III. Latent heat is L = Q/m, so its unit is J kg⁻¹ ⇒ C–I. From the heat-conduction relation Q/t = kA(ΔT)/l, the unit of thermal conductivity k is J m⁻¹ K⁻¹ s⁻¹ ⇒ D–IV. Thus the matching is A–II, B–III, C–I, D–IV. Correct option: D.
