Which of the following statement(s) is/are incorrect?
Options:(select one or more)
Answer:
B, C, D
Solution:
(a) δ qrev = 0 so dS = 0: true statement. (b) q + w = Δ U is path independent: incorrect. (c) Δ U = 0 does not mean Δ T = 0; an exothermic reaction in an adiabatic rigid vessel raises T: incorrect. (d) An irreversible adiabatic process has Δ Suniv > 0 (it equals zero only if reversible): incorrect. Ans: (b), (c), (d).
