Question

the particles in liquid s and gases show random motion. what does that means and why does it happens

Answer 1

In liquids, particles are quite close together and move with random motion throughout the container. ... With an increase in temperature, the particles gain kinetic energy and vibrate faster and more strongly. The attractive force in solids need not be stronger than in liquids or gases.

Answer 2

The particles in the liquid and in the gases show the random motion because the intermolecular distance between the molecules is less due to which they can move freely and in case of gases they intermolecular force is very weak compare to liquid...
