Question

Even two or three cups of potassium permanganate can impart colour to a large volume of water. Which characteristic property of particles of matter is illustrated by this observation? Define that property.

Answer 1

From the above-given observation i.e, even two or three cups of potassium permanganate can impart colour to a large volume of water, we say that:

• The matter is made up of small particles.
• The particles diffuse quickly into the water through the process of Diffusion.
• Diffusion: Diffusion is a physical process that refers to the net movement of molecules from a region of high concentration to one of lower concentration.
• There are millions of small particles contained in each crystal of potassium permanganate which can not be seen with the naked eye.
• These particles diffuse quickly in all the directions in the given solvent i.e, water by diffusion, imparting colour to a large volume of water.
