When a crystal of potassium permanganate is placed at the bottom of the water in a beaker, the water in the whole beaker turns purple on its own, even without stirring. This is an example of :

(a) distribution (b) intrusion (c) diffusion (d) effusion

Solution

(c) Diffusion

When we place Potassium Permanganate crystals into the water, it's purple colour spreads throughout the water. This shows the diffusion property of particles of water and Potassium Permanganate, as due to this property only the dissolution and spreading of the colour of Potassium Permanganate takes place.
