- A.Collisions between molecules are inelastic
- B.The volume of molecules is significant
- C.There are intermolecular forces of attraction
- D.Collisions between molecules are perfectly elastic
Show correct answer & step-by-step solution
Correct answer: D — Collisions between molecules are perfectly elastic
Solution
A fundamental postulate of the kinetic theory of gases is that the collisions between gas molecules and between the molecules and the walls of the container are perfectly elastic, meaning kinetic energy is conserved.
