Choose the correct answer. A thermodynamic state function is a quantity
(i) used to determine heat changes
(ii) whose value is independent of the path
(iii) used to determine pressure volume work
(iv) whose value depends on temperature only.
Thermodynamic state functions are functions that depend only on the initial and final state of the system. It is independent of the path taken to change from one state to another.
Thus, answer is (ii) whose value is independent of path
