Kinetic Theory

The average thermal energy for a mono-atomic gas is: (kBk_B is the Boltzmann constant and TT is the absolute temperature)

  1. A.12kBT\dfrac12 k_BT
  2. B.32kBT\dfrac32 k_BT✓
  3. C.52kBT\dfrac52 k_BT
  4. D.72kBT\dfrac72 k_BT

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
