Question 15 (a) Illustrate using three boxes the Zeroth Law of Thermodynamics and state its result. (2) (b) State the Second Law of Thermodynamics in terms of entropy. (2) (c) One mole of H2O(l) is supercooled to a liquid at -100C at 1 bar pressure. The transformation H:0(1) H2O(s) is suddenly observed to occur at -100C. The freezing temperature of water at this pressure is 0.00C. By calculating ASsystem, ASsurroundings, and A Suniverse, verify that this transformation is spontaneous at -100C. Assume that the surroundings are at -100C. Given: Cp.m(H2O(1)) = 75.3 JK' moli Com(H2O(s)) = 37.71 Kmol! AH"fusion = 6.008 kJ mol! (16) (d) The entropy change of the Universe was found to be +0.82 J mol' k'at -10C. Contrast and comment on the two values obtained for H2O(l) supercooled and allowed to freeze at 0C; at -10C and at -100C. (2) [22]
