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

Random, straight-line
motion? The gas particles move
in straight lines between
collisions. Recall: straight-line
motion implies that no forces
are acting on the particle.
Therefore the ans is A. According to the postulation 'gas molecules collide with one another and with the walls of the container whereby the collision is perfectly elastic
Yeah in this question ,the answer given in the question is B.force of repulsion exist. but when I watched the videos ,that brilliant dude there said A.collision are perfectly elastic is correct ,please we should be setting about the answers please so incase we see then in jamb we can be setting of which to pick , thanks as you make changes
