Question

Describe an activity to prove that particles of matter are very small with proper process

Answer 1

we will take a beaker A filled with water

then we will add few drops of colour in it and mix it well

after that take another beaker B filled with clear water and then take some of the solution from beaker A and pour it into beaker B

repeat this process with different beakers

you will observe that many beakers contain clear water will get coloured and this will become lighter and lighter ...

which proves that matter is made up of very small particles which cant be seen by a naked eye

Answer 2

Answer:

Explain Procedure:

1.Dissolve a few crystals of potassium permanganate in 100 ml of water.

2.Take out approximately 10 mL of this solution and add it to 90 mL of clear water taken in another beaker.

3.Now from this solution, take 10 ml of the solution and add it 90 ml of water taken in another beaker.

4. In the same manner Keep diluting the solution like this 5 to 8 times.

Observation:

This experiment shows that just a few crystals of potassium permanganate can colour a large volume of water (about 1000 L).

Conclusion:

This activity proves that matter is made up of tiny particles. So we conclude that there must be millions of tiny particles in just one crystal of potassium permanganate, which keep on dividing themselves into smaller and smaller particles. Ultimately a stage is reached when the particles cannot divide further into smaller particles.
