According to the kinetic theory of gases, when two molecules of gas collide with each other then

Options

  1. AKinetic energy is conserved but momentum is not conserved.
  2. Bneither kinetic energy nor momentum is conserved.
  3. Cboth kinetic energy and momentum are conserved.
  4. Dmomentum is conserved but kinetic energy is not conserved.

Correct answer

C. both kinetic energy and momentum are conserved.

Step-by-step solution

Concept-based. Collisions are elastic so energy is conserved and momentum conservation always occurs if the external force is zero.
