Match List-I with List-II.
$$\begin{array}{|l|l|l|l|}\hline & \text{List-I} & & \text{List-II} \\ \hline \text{A.} & \text{Heat capacity of body} & \text{I.} & \text{J kg}^{-1} \\ \hline \text{B.} & \text{Specific heat capacity of body} & \text{II.} & \text{J K}^{-1} \\ \hline \text{C.} & \text{Latent heat} & \text{III.} & \text{J kg}^{-1}\text{K}^{-1} \\ \hline \text{D.} & \text{Thermal conductivity} & \text{IV.} & \text{J m}^{-1}\text{K}^{-1}\text{s}^{-1} \\ \hline \end{array}$$
Choose the correct answer from the options given below:
Answer: (D) (A)-(II), (B)-(III), (C)-(I), (D)-(IV)
- (A) Heat capacity $= \dfrac{\Delta Q}{\Delta T}$: $\text{J K}^{-1}$ → (II)
- (B) Specific heat capacity $= \dfrac{\Delta Q}{m\Delta T}$: $\text{J kg}^{-1}\text{K}^{-1}$ → (III)
- (C) Latent heat $= \dfrac{\Delta Q}{m}$: $\text{J kg}^{-1}$ → (I)
- (D) Thermal conductivity, from $\dfrac{\Delta Q}{\Delta t} = \dfrac{KA\Delta T}{L}$: $K = \dfrac{\Delta Q\,L}{\Delta t\,A\,\Delta T}$, unit $\text{J m}^{-1}\text{K}^{-1}\text{s}^{-1}$ → (IV)
