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
Explication
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.
