Answer 1

Explanation:

Mark it as brainliest .Please

Answer 2

Aim = to show that the particle of matter are small in size

Material required : water, beaker, a few crystals of potassium permanganate

Procedure :

(a) Take a few crystals of KMnO4 and dissolve them in 100ml of water in a beaker. Mark this solution as A

(b) Take 10ml of this solution A in another beaker or test tube and add it into 90ml of water. Mark this solution as B.

(c) repeat the activity four time down the colour that change everything

Observation :

(a) We obtain a purple colour solution after the adding KMnO4 to the water

(b) After each dilution, colour solution get faded as potassium permanaganate

particle get decreased per unit volume

Conclusion :

this activity prove that the potassium permanganate are made up of small particle which keep on sepreading in the water by the process of diffusion
