The average thermal energy for a mono-atomic gas is : ( k B is Boltzmann constant and T , absolute temperature)

Options

  1. A3 2   k B T
  2. B5 2   k B T
  3. C7 2 k B T
  4. D1 2   k B T

Correct answer

A. 3 2   k B T

Step-by-step solution

Average thermal energy = 3 2 k B T where 3 is translational degree of freedom for monoatomic gas total degree of freedom f = 3 (translational degree of freedom)
