12. Which of the following conditions should be satisfied by the temperature T of a system of N non-interacting particles occupying a volume V, for Bose-Einstein condensation to take place?
(where, m is the mass of each particle of the system, kB is the Boltzmann constant, h is the Planck's constant and $$\xi $$ is the well known zeta function.)
