Unformatted text preview: o C 3. 1.000 mol of benzene freezes at 5.5 o C in a vessel that is immersed in an ice-water mixture. Calculate the entropy changes from the benzene, the ice-water mixture and the total entropy change for the universe (for benzene T f =5.5 o C and D H f =125 J/g). 4. An iceberg with a mass of 1.00 x 10 9 kg at a temperature of 0 o C drifts into the Gulf Stream, which is at a temperature of 20 o C. After several weeks, there remains only water at 20 o C. What is the entropy change in the universe associated with the disappearance of the iceberg? Note : 1 L.atm = 101.3 J, 1 L.Pa = 1 J. Missing D H and C p values may be found in Appendix D. C p C v = R for any ideal gas....
