Stuff for Friday, June 3, 2011 Quiz today on T7, T8 Final exam is here next Thursday from 3:30pm-5:18pm. Covers Q12-Q14 and T1-T8 Review sheets plus your own annotations Open office hours in M2048 next week; just drop by or email to be sure I really enjoyed having all of you in class. Thanks for the questions! T8, T9 stuff: Entropy S = k b ln Ω , so Ω = e S / k b ; S /∂ U 1 / T defines temperature Characteristic temperature T ε ε/ k B ; dof’s switched off if T ε ± T Entropy of a monatomic gas Ω( U , V , N )
