Physics 2C, Waves ...Optics -- Winter 2007 Instructor: B. Grinstein Quiz # 8 INSTRUCTIONS: Fill, tear and return the bottom strip of the front page with your scantron. Keep the top portion of the front page and the rest of the quiz. Use a pencil #2 to fill your scantron. Write your code number and bubble it in under "EXAM NUMBER". Bubble in the quiz form (see letter A -- D at bottom of page) in your scantron under "TEST FORM" Useful numbers: k = 1.38 × 10 - 23 J/K, N A = 6.022 × 10 23 , R = N A k = 8.314 J/K · mol, 1 u = 1.66 × 10 - 27 kg, 1 atm = 101.3 kPa 1) Which of the following is a FALSE statement? A) The difference in entropy between two states of a system is independent of the path between the two states. B) Entropy can be measured in units of J/K. C) Entropy is a quantitative measure of disorder. D) The entropy of an isolated system is conserved, i.e., constant. E) The total entropy change in one cycle of a Carnot engine is zero. 2) What is wrong with this statement: A heat engine extracts 900J from a hot reservoir at 300 K and rejects 700 J of heat to a cold reservoir
