Question 6

Gas Laws

The basic assumption in the kinetic theory of gases that the collisions of the gaseous molecules are perfectly elastic implies that the

  1. A.forces of attraction and repulsion are in equilibrium
  2. B.gaseous molecules can occupy any available space
  3. C.gaseous molecules will continue their motion indefinitely
  4. D.gases can be compressed
Show the answer and explanation

Answer: C (gaseous molecules will continue their motion indefinitely)

Explanation

In a perfectly elastic collision no kinetic energy is lost, so the molecules never slow down and keep moving.
