Which of the following statement(s) is/are incorrect?
Options:(select one or more)
Answer:
B, C, D
Solution:
(a) q + w = Δ U, a state function: true (so not incorrect). (b) With q = w = 0, Δ U = 0, but T can still change (e.g. an exothermic reaction in an adiabatic rigid vessel): incorrect. (c) S is a state function, so Δ Ssys is the same for both paths: incorrect. (d) An adiabatic irreversible process has Δ Ssys > 0: incorrect. Ans: (b), (c), (d).
