Question

Helmhotz free energy is not a state function.

• A. True
• B. False

Answer 1

The correct option is B False

In thermodynamics, a state function or function of state is a function defined for a system relating several state variables or state quantities that depends only on the current equilibrium state of the system. State functions do not depend on the path by which the system arrived at its present state. A state function describes the equilibrium state of a system.The following are considered to be state functions in thermodynamics:

1. Mass
2. Energy (E)
3. Enthalpy (H)
4. Internal energy (U)
5. Gibbs free energy (G)
6. Helmholtz free energy (F)
7. Entropy (S)
8. Pressure (P)
9. Temperature (T)
10. Volume (V)
