Asystem consists ofnidentical partides. each particle can have only one of energies: ,2,3, for given temperature 7 find the average energy of the system, the partition function z, free energy f, entropy s, internal energy u of the system, of the system. finally, determine an expression for the heat capacity of the system e=ε 1-e-e/kt
