2.12. Show that below the transition temperature the entropy of a Bose gas is given by 5 =NK 3/2 (T) 3/2 (7) 1. 11/2 T Since the number of excited particles is given by 3/2 = N (7) /, S Nk- Nex = N show that the entropy per excited particle is given by 5 13/2 k 1.28k. 311/2 S Nex Discuss the connection between this result and the two-fluid model of superfluid *He. 2.12.
