Question

Which of the following expressions regarding entropy is not correct?

• A. $\Delta s_{system} = \frac{q}{T}$
• B. $\Delta s_{system} = \Delta s_{total} + \Delta s_{surrouding}$
• C. $\Delta s = S_{final} - S_{{in}itial}$
• D. $\Delta s_{total} = \Delta s_{system} + \Delta s_{surrounding}$

Answer 1

Answer: (B)

$\Delta s_{system} = \Delta s_{total} + \Delta s_{surrouding}$

Answer 2

: $\Delta S_{system} = \Delta S_{total} - \Delta S_{surrounding}$
