A basic postulate of the kinetic theory of gases is that the molecules of a gas move in straight lines between collisions. This implies that?
collisions are perfectly elastic
forces of repulsion exist
forces of repulsion are in equilibrium
collision are inelastic
Correct answer is A
Collisions between gas particles or collisions with the walls of the container are perfectly elastic. None of the energy of a gas particle is lost when it collides with another particle or with the walls of the container.
