Which of the following thermodynamic variables is a state function?
- A.Work done
- B.Heat
- C.Internal energy
- D.Power
Show correct answer & step-by-step solution
Correct answer: C — Internal energy
Solution
A state function depends only on the initial and final states of the system, not on the path taken. Internal energy is a state function, whereas work and heat are path-dependent quantities.
