Problem Set 7 UC Berkeley Page 2 the maximum possible value, explain whether the entropy increases or decreases with respect to state B. (iv) Next, assume that the system has an infinite number of possible energy levels of increasing energy. In this case, when the total energy of the 3 molecules is increased does the entropy always increase, or does it sometimes increase and sometimes decrease? Explain your answer. 3. A more accurate version of Stirling’s approximation is given below: ln N!= N ln N − N + ln( 2πN ) Estimate, by trial and error, how big N has to be for the error introduced by neglecting the last term to be less than 1% of the value of ln N!

Problem Set 7 UC Berkeley Page 3 4. * A reversible process takes place within a system containing 2 moles of a molecule, with the absorption of 10 kJ mol-1 of heat from the surroundings at 300K. What is the ratio of the multiplicities of the initial and final states of the system...
