Answer:
Dissolving a solid in a liquid:
When a crystal of potassium permanganate is placed in a beaker of water, the water slowly turns purple on its own, even without stirring.
Both potassium permanganate crystal and water are made up of tiny particles.
When the potassium permanganate crystal is put in water, its particles separate from one another.
These purpled colored particles of potassium permanganate spread throughout water making the whole water look purple.
Actually, on dissolving, the particles of potassium permanganate get into the spaces between the particles of water.
So it is concluded that the particles are moving or they are in motion.
