Question

Suggest an activity to explain particles of matter are very very small.​

Answer 1

Answer:

Take 1 L of water in a beaker. ... - This very small crystals of KMnO4 change color of whole water. - This is because each crystal of potassium permanganate breaks into smaller & smaller particles and react independently with water. - From this we can conclude that each substance is made of much smaller particles.

Answer 2

Explanation:

Matter is made up of very small particles: All matter is made up of very small particles that are not visible to naked eye. We can prove this by performing the following experiment: Take two or three crystals of potassium permanganate and add in 100ml of water. We will see that the colour of the water gets changed.
