Answer 2

Answer:

Brownian motion is almost absent in solids.

Explanation:

Brownian motion is a random and uncontrolled movement of suspended particles in a fluid where they constantly collide with other molecules.

The particles are microscopic in size which move randomly in the fluids (liquid and gas). Diffusion of pollutants in the air and pollen grain sin water is an example of this motion. The Brownian motion causes the particles to constantly move in the fluid and not settle down.
