Molar speciﬁc heat capacity of a substance is _________ .

(1/μ)(∆T/∆Q)

(1/μ)(∆Q/∆T)

μ(∆Q/∆T)

μ(∆T/∆Q)

Solution

Correct option is B

Molar specific heat capacity is the amount of heat required to raise the temperature of one mole of a substance by one degree (Celsius or Kelvin). In mathematical terms, it is usually denoted CCC and defined as:
$C = \frac{1}{\mu} \cdot \frac{\Delta Q}{\Delta T},$
where ΔQ is the heat energy added, ΔT is the change in temperature, and μ represents the amount of substance in moles. This concept is critical because different substances have varying capacities for storing thermal energy, and this property influences how they respond to heating or cooling processes. For instance, a substance with a high molar specific heat capacity can absorb more heat before its temperature rises significantly.
