Q21. Consider a gas of atoms obeying Maxwell-Boltzmann statistics. The average value of e over all the moments p of each of the particles (where a is a constant vector and a is the magnitude, m is the mass of each atom, T is temperature and k is Boltzmann' s constant) is, a mkT a mkl (a) one (b) zero (c) e (d) e
