6.1 Choose the correct answer. A thermodynamic state function is a quantity
(i) used to determine heat changes
(ii) whose value is independent of path
(iii) used to determine pressure volume work
(iv) whose value depends on temperature only.
A state function refers to the equilibrium state of a system. A thermodynamic state function is a quantity whose value is independent of path.
Like- depends on the state of the system, not on the path.
So, the correct option is (ii)
