For a system of constant composition, the pressure (P) is given by.
(a)$-\left(\frac{\partial \mathrm{U}}{\partial \mathrm{S}}\right)_{\mathrm{V}}$
(b)$-\left(\frac{\partial \mathrm{U}}{\partial \mathrm{V}}\right)_{\mathrm{S}}$
(c)$\left(\frac{\partial \mathrm{V}}{\partial \mathrm{S}}\right)_{\mathrm{T}}$
(d)$\left(\frac{\partial \mathrm{U}}{\partial \mathrm{V}}\right)_{\mathrm{T}}$
Answer
Answer: B ✓ checked by 4AB · confidence high
Explanation
From dU = TdS − PdV, P = −(∂U/∂V)_S (b).
