NEET Chemistry Thermodynamics MCQ Question
Among the following, the set of parameters that represents path function is: (A) q + w (B) q (C) w (D) H − TS
(B) and (C)
(A) and (D)
(B), (C) and (D)
(A), (B) and (C)
Correct Answer
Detailed Explanation
q + w = ΔU (state function). q (heat) and w (work) are path functions — their values depend on the path taken, not just initial and final states. H − TS = G (Gibbs free energy) is a state function. So only q and w are path functions.
