Using the first law of thermodynamics dU = TdS - PdV and the definitions of thermodynamic potentials, compute the quantity χ = (∂T/∂V)S + (∂T/∂P)S + (∂P/∂T)V + (∂V/∂T)P. Which of the following does χ equal using Maxwell's relations?
- 1(∂S/∂V)T + (∂S/∂P)T + (∂V/∂S)P + (∂P/∂S)V
- 2(∂S/∂V)T + (∂S/∂P)T + (∂V/∂S)P - (∂P/∂S)V
- 3(∂S/∂V)T - (∂S/∂P)T + (∂V/∂S)P + (∂P/∂S)V
- 4(∂S/∂V)T - (∂S/∂P)T + (∂V/∂S)P - (∂P/∂S)V✓
Correct answer
(∂S/∂V)T - (∂S/∂P)T + (∂V/∂S)P - (∂P/∂S)V
