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 and attraction are in equilibrium
collisions are inelastic

According to one of the kinetic theories of gases, When collisions occur, the molecules lose no kinetic energy; that is, the collisions are said to be perfectly elastic.
