Molecules of an ideal gas have no potential energy because:

  1. they have no mass
  2. there are no intermolecular forces (except during collisions)
  3. they are at rest
  4. they are very hot
Answer

B) there are no intermolecular forces (except during collisions)

So internal energy = total KE. SLO P-11-C-05 · Understanding
