Question

Assertion Specific heat capacity and molar specific heat capacity both have same units.
Reason Specific heat capacity and molar specific heat capacity both do not depend on mass.

• A. Both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
• B. Both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.
• C. Assertion is correct but Reason is incorrect.
• D. Assertion is incorrect but Reason is correct.

Answer 1

Answer: (D)

Specific heat capacity $s=\frac{\Delta Q}{m\Delta T}$,
where $m$ is mass of substance. Its SI unit is $Jk{g}^{-1}{K}^{-1}$.
Molar specific heat capacity $C=\frac{\Delta Q}{\mu \Delta T},$
where $\mu$ is number of moles. Its SI unit is $Jmo{l}^{-1}{K}^{-1}$.
Both of these are constants characteristics of a substance and are independent of its mass. Therefore, Assertion is incorrect but Reason is correct.
