Question

Which of the following is not a thermodynamic function?

• A. Enthalpy
• B. Work done
• C. Gibbs energy
• D. Internal energy

Answer 1

The correct option is B

Work done

Explanation for correct option

(B) Workdone

Thermodynamic functions

• The basic function of thermodynamic potential is a quantity used to represent the state of a system.
• Internal energy U, enthalpy H, Helmholtz free energy F, and Gibbs free energy G are the four fundamental functions.
• Work done, on the other hand, is a path function that means that the system depends on the path taken while it changes from the initial state to the final. state.

Explanation for incorrect option

• Thermodynamic functions include enthalpy, Gibbs energy, and internal energy.
• Hence, options (A), (C), and (D) are incorrect.

Hence, option (B) is correct. Work done is not a thermodynamic function.
