Question

How can you show that particles of matter attract each other?​

Answer 1

Experiment

Take a beaker and fill it with 10 mL of water and add two to three crystals of potassium permanganate.

Now take few measuring cylinders and label them as 1,2,3, 4 … and so on.

Next, fill these cylinders with 50 mL of water. Transfer 5 mL of the solution to the measuring cylinder 1 which has 50 mL of water from the beaker. Mix the water and the solution.

Now, take out 5 mL of the solution from cylinder 1 using a pipette and transfer it into measuring cylinder 2. Shake this mixture.

Take out 5 mL of the solution from cylinder 2 using a pipette and transfer it into measuring cylinder 3. Shake this mixture.

Carry on this process of dilution of the solution in a similar manner.

Observation

The solution held in the various measuring cylinders are all colored, even though the color gets fainter and fainter with successive dilution.

Conclusion

It can be concluded that a small crystal of potassium permanganate contains a very large number of tiny particulate matter showing the properties of the parent substance.

${\red{\underline{\underline{\bold{Answer:-}}}}}$

take a piece of chalk, a cube of ice, and an iron nail,no beat it with a hammer..we will find that it is very easy to break the piece of chalk into smaller pieces,it requires more force to break a cube of ice whearas an iron nail will not break at all even with a large force..this shows that force of attraction between the particles of ice is a little strong whereas the force of attraction between the particles of an iron nail is very strong ... conclusion , the force of attraction is maximum between the particles of solids and minimum in the particles of gases matter ...

hope it helps you..
