Explanation:
dU=TdS-pdV (given)
To prove = 1) (at constant U)
2) (at constant V)
Solution: 1)
dU=TdS-PdV
Derivative of constant is zero.
Given that internal energy is ,U = constant
(hence proved)
Solution: 2)
dU=TdS-PdV
Differentiating with respect to dU, we get:
Derivative of constant is zero.
Given that volume is constant , V= constant
(hence proved)
