Which of the following assumptions is NOT part of the kinetic theory of ideal gases?
- A.Collisions between molecules are perfectly elastic
- B.Molecules exert no intermolecular forces on each other
- C.The volume of molecules is negligible compared to the container volume
- D.Molecules move in circular paths
Show correct answer & step-by-step solution
Correct answer: D — Molecules move in circular paths
Solution
- Kinetic theory assumes molecules move in random straight-line motion.
- Collisions are assumed to be perfectly elastic.
- Intermolecular forces are assumed to be zero except during collisions.
- The assumption of circular motion is incorrect.
- Hence the answer is (D).
