A thermodynamic system undergoes a process from an initial state (i) to a final state (f). If the system's internal energy (U) increases by 10 J and the work done (W) on the system is 5 J, what is the change in the system's entropy (ΔS)?

Answer Options

A. \( Delta S = \frac{Q}{T} \)
B. \( Delta S = \frac{W}{T} \)
C. \( Delta S = \frac{U}{T} \)
Correct Answer D. \( Delta S = \frac{Q}{T} + \frac{W}{T} \)
Correct Answer
D
Correct Option:
\( Delta S = \frac{Q}{T} + \frac{W}{T} \)
