The three lowest non-degenerate energy levels of a certain molecule areE1 =0,E2 =?>0,andE3 =10?. (a)Showthatatsufficientlylow temperatures (how low?) only levels E1 and E2 are populated. Estimate this temperature kTc in terms of the number N of molecules and ?. Use Boltzmann statistics. (b) At any temperature T, what is the average energy of a molecule?
