Q24. aOne-dimensional Ising model with N spins, at very low temperatures when l spins are aligned parallel to each other. There will be a few spin flips with each fli is E =-NJ +2r.J and the number of configuration is C ;r varies from 0 to N. The g an energy 2J. In a configuration with r spin flips, the energy of the system partition function is (a) k,T) Sinh kT) J cosh kT (b) e-NIIk,T c) (d)
