MCQ
Choose the correct answer. A thermodynamic state function is a quantity
  • A
    used to determine heat changes
  • B
    used to determine pressure volume work
  • ✓
    whose value is independent of path
  • D
    whose value depends on temperature only.
✓

Answer

Correct option: C.
whose value is independent of path
c
A thermodynamic state function is a quantity whose value is independent of a path. Functions like $p, V, T$ etc. depend only on the state of a system and not on the path. Hence, alternative $(iii)$ is correct.
