Question

5. (a) Distinguish between Fermions and Bosons. Give three examples of (b) each. How do you distinguish between them? A thermodynamic system consists of two particles which may occupy any of the three energy levels = ne, n = 0.1, 2. The lowest energy state, &, = 0, is doubly degenerate. The system is in thermal equilibrium at temperature T. Determine the partition function of the system if the particles obey (1) Fermi - Dirac (FD) Statistics (ii) (iii) (iv) Bose - Einstein (BE) Statistics Maxwell - Boltzman (MB) Statistics Determine the energy of the system if the particles obey Bose-Einstein Statistics.

Answer 1

(a) Fermions are spin  half particles while bosons are integral spin particles, fermions are an electron, proton etc and bosons photons, phonons and alpha particles

Bosons and fermions are an indistinguishable particle and obey Bose-Einstein statistics and Fermi-Dirac statistics respectively, Classical particles are a distinguishable particle and obey Maxwell distribution. The partition function is defined as the summation of all microstates. Here I am attaching sheet of the solution of this question
