Question

Molar specific heat capacity $C$ of a substance having $\mu$ moles

• A. can be represented by $\frac{1}{\mu }\frac{\Delta Q}{\Delta T}$
• B. is different for different amount of substance
• C. can be varied depending upon change in the temperature rised
• D. Both (a) and (c)

Answer 1

Answer: (D)

Heat capacity per mole of the substance is given by
$C=\frac{1}{\mu }\frac{\Delta Q}{\Delta T}$
where, $C$ is molar specific heat capacity of the substance. It is independent of the amount of substance.
But it depends on the nature of the substance, its temperature and the condition under which heat is supplied.
