Problem 2: Consider four independent magnetic atoms in a magnetic field B parallel to z axis at temperature T. The energy of single magnetic atom is E = –m.B. The magnetic moment of a single atom can take only on one of the two values: mz = ±mo. (a) Calculate the partition function (b) What are the probabilities of finding the six atoms in the state of total magnetization M, = D = -4mo, 0, 4mo correspondingly?
Sort: Consider 1.50 mols of a substance in thermal equilibrium at a temperature of 87.0 °C whose atoms can occupy only two energy levels separated by 5.00x102 eV, where 1 eV (electron volt) is an energy unit equal to 1.60x1019 J. kB = 1.38x10 23 J/K , NA = 6.02x1023 mol! %3D Eg - a) Find the probability of occupation of the ground state with energy E1 and the 1st excited state with energy E2? b) How many atoms in the substance (on average) are in 5.00x102 eV the ground state and in the 1st excited state?
