# Choose the correct answer. A thermodynamic state function is a quantity

Question:

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.

Solution:

A thermodynamic state function is a quantity whose value is independent of a path.

Functions like pVT etc. depend only on the state of a system and not on the path.

Hence, alternative (ii) is correct.
