Question

The true statement amongst the following is:

• A. $S$ is a function of temperature but $\Delta S$ is not a function of temperature.
• B. Both $\Delta S$ and $S$ are functions of temperature.
• C. Both $S$ and $\Delta S$ are not functions of temperature.
• D. $S$ is not a function of temperature but $\Delta S$ is a function of temperature.

Answer 1

The correct option is B Both $\Delta S$ and $S$ are functions of temperature.

Entropy is a function of temperature, at any temperature, the entropy can be given as:
$S_T=\underset{0}{\overset{T}{\int }}\frac{nCdT}{T}$
Change in entropy is also a function of temperature, at any temperature, the entropy change can be given as:
$\Delta S=\underset{}{\overset{}{\int }}\frac{dq}{T}$
