Question:medium

The INCORRECT assumption in the kinetic theory of gases is

Show Hint

"Elastic collision" by definition means kinetic energy is conserved. If you know collisions are elastic (Postulate B), then you immediately know Postulate D must be false.

  • Interactions between molecules is negligible
  • Collisions between molecules are elastic in nature
  • Molecules move in straight lines between any two collisions
  • During collisions total kinetic energy is not conserved
  • Gas molecules are in incessant random motion
