Answer 2

Answer:

Adding crystals of potassium permanganate to a 250ml of water in a beaker. We can observe that the color disperses in the water slowly and also the size of potassium permanganate reduces.

Hence we can say that potassium permanganate is made up of tiny particles which get dissociated when added to the water, here the color of the water can be considered as an indicator.

Explanation:

The activities which can show that matter is made up of tiny particles are-

• Coloring with crayons results in transfer of color onto the coloring surface.
• Writing with pencil on paper reduces the sharpness of pencil lead.
• chalk reduces as used on board and when dusted with duster the chalk power falls off.
• carpenter cutting wood with saw creates sawdust.
• When glass is broken we can find many irregular small glass pieces.
• When we use perfume the particles are sprayed over which gives a fragrance smell to the clothes and even all over the room.

All these activities indicate that these substances are made up of very tiny particles.
