2. G’s jokes are represented by 1 mole of a solid at temperature T1 < 273K. They are so savage that when you put them in an ocean of mass M,

initially at temperature T2 > 273 K, 2 / 3 of that ocean freezes (and the jokes remain solid). You may assume both cm of liquid ocean and

∆ Hm of melting ocean at Tmelt = 273 K are known.

a) What is the molar specific heat of G’s jokes?

b) What is the change in the entropy of the universe as a result of G’s jokes interacting with

the ocean?

c) Challenge mode (do this last). Is your answer in b) consistent with the second law of

thermodynamics? Prove why or why not.

2. The heat capacity of one mole of aluminum at low temperature (below 50 K) follows the form CV = aT+bT3 where a = 0.00135 J/K2 and b = 2.48×10-5 J/K4. (The first term comes from the free electrons and the second term is due to lattice vibrations.) Use this expression to derive a formula for the molar entropy of aluminum as a function of temperature, assuming that the entropy at 0 K is zero. Finally, determine the ratio of...
