alleryWhich of the following is **not** a state function?
AEnthalpy $H$
BWork $W$
CEntropy $S$
DInternal energy $U$
Answer & Solution
Correct answer: B. Work $W$
State functions depend only on the current state of the system, not on the path taken to reach it.
Internal energy, enthalpy, entropy and Gibbs free energy are all state functions.
Heat $q$ and work $W$ are path functions — their values depend on the process by which the change occurs.
