Which of the following statement(s) is/are incorrect?

Options:(select one or more)

Answer:
A, B, C, D
Solution:

(a) Combustion is exothermic, with q = 0 and w = 0 the heat raises T: incorrect. (b) Two adiabatic paths between the same states would require Δ S = 0 and Δ S > 0 at once: impossible, so incorrect. (c) A reaction changes bond energies, so Δ U ≠ 0 even for ideal gases at constant T: incorrect. (d) Expansion into vacuum changes V with w = 0: incorrect. Ans: (a), (b), (c), (d).
