Which assumption is NOT part of the kinetic molecular theory of an ideal gas?
- A. Gas molecules are in constant random motion
- B. Collisions between molecules are perfectly elastic
- C. There are strong attractive forces between gas molecules
- D. The volume of the molecules is negligible compared with the volume of the container
Explanation
An ideal gas is defined by the absence of intermolecular forces, which is precisely why it obeys the gas laws exactly. Real gases do have such forces, which is why they deviate at high pressure and low temperature. The other three assumptions are all part of the model.
