Solution
Correct Answer:
(∂T/∂V)S=−(∂P/∂S)V
Maxwell relations are derived from the fact that thermodynamic potentials (like U) are state functions with exact differentials.
- From the first law: dU=TdS−PdV.
- Since dU is an exact differential, the mixed partial derivatives must be equal: (∂V∂T)S=(∂S∂(−P))V=−(∂S∂P)V This identifies a deep connection between the temperature-volume relationship and the pressure-entropy relationship.
This hard difficulty physics question is from the chapter thermodynamics, covering the topic of maxwell relation hard. It appeared in the 2025 exam.
