Before we understand how it is work we need to know about the matter.
MATTER
In short everything present in the universe is Matter. The matter has some mass & volume so it occupies space.
Example of matter
( All solid, liquid & gas ) Smartphone, Gas cylinder, Water bottle etc. All matter is made up of particles.
How salt (matter) dissolve in water (matter)?
This phenomenon we can generally observe when we prepare lemonade, coffee & any other. For this, we are doing an activity.
Here we take a 100 ml beaker & fill it half with water & put one teaspoon salt in it.
Now stirrer the solution & what we get? We get salt is completely dissolved in water. How it is possible? Let's discuss.
NOTE:- It totally depends on the type of matter that we are using.
 |
| Beaker filled with water & voids is present between particles of water because here form of water is liquid. |
 |
| Now salt particles placed into the voids between particles of water. |
As we discuss all matters are made up of
particles.
In the above figure particles of water is showing in a beaker. Water is in
liquid form & we know some space is available between particles of water (liquid).
When salt particles enter in a beaker then they place itself between the
particles of water.
According to this, all particles of salt fill the voids (gaps)
present between the particles of water & dissolve itself.

Here the initial & final stage of activity is shown, how one matter dissolves in other matter. |
Finally, we got the result & we may look at how salt dissolves itself into water.
