Which among the following is not an exact differential?

A

Q(dQ=heat abosorbed)

B

U (dU=change in internal energy)

C

S (dS=entropy change)

D

G (dG=Gibbs free energy change)

Text Solution

Verified by Experts

The correct Answer is:
A
Heat 'Q' is a pathh dependent function, hence its exact differentiation is not possible, However, internal energy, entropy and gibbs free energy are state functions, hence can be differentiated exactly.
