Question

Match List-I with List-II.

List-I	List-II
(A) Heat capacity of body	(I) \( J\,kg^{-1} \)
(B) Specific heat capacity of body	(II) \( J\,K^{-1} \)
(C) Latent heat	(III) \( J\,kg^{-1}K^{-1} \)
(D) Thermal conductivity	(IV) \( J\,m^{-1}K^{-1}s^{-1} \)

• A. (A)-(III), (B)-(I), (C)-(II), (D)-(IV)
• B. (A)-(I), (B)-(III), (C)-(II), (D)-(IV)
• C. (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
• D. (A)-(II), (B)-(III), (C)-(I), (D)-(IV)

Hint:

The formulae for heat capacity, specific heat, and thermal conductivity can be used to relate physical properties of substances.

Answer 1

The Correct Option is D

We are asked to match physical quantities with their SI units.

Step-by-Step Solution:

(A) Heat capacity of a body:

\[ \text{Unit: } \frac{\text{Joule}}{\text{Kelvin}} = \text{J K}^{-1} \] Hence, (A) → (II)

(B) Specific heat capacity of a body:

\[ \text{Unit: } \frac{\text{Joule}}{\text{kilogram} \cdot \text{Kelvin}} = \text{J kg}^{-1} \text{K}^{-1} \] Hence, (B) → (III)

(C) Latent heat:

\[ \text{Unit: } \frac{\text{Joule}}{\text{kilogram}} = \text{J kg}^{-1} \] Hence, (C) → (I)

(D) Thermal conductivity:

\[ \text{Unit: } \frac{\text{Joule}}{\text{metre} \cdot \text{second} \cdot \text{Kelvin}} = \text{J m}^{-1} \text{K}^{-1} \text{s}^{-1} \] Hence, (D) → (IV)

Final Matching:

List-I	List-II
(A) Heat capacity of body	(II) J K-1
(B) Specific heat capacity of body	(III) J kg-1 K-1
(C) Latent heat	(I) J kg-1
(D) Thermal conductivity	(IV) J m-1 K-1 s-1

Final Answer:

\[ \boxed{(A) \to (II), \quad (B) \to (III), \quad (C) \to (I), \quad (D) \to (IV)} \]
