How will you demonsrate that interparticle spaces are present in a matter ?
Answers
Aim:
To prove that matter have space between them.
Apparatus required :
beaker, water,salt,glass rod
Procedure :
1. Take 100 ml of water in a beaker .
2. Mark the level of the water with marker pen on the beaker.
3. Take 100gms of salt and add it to water in the beaker.
4. Dissolve the salt by stirring it with glass rod.
5. When all the salt has dissolved, we get salt solution.
Observation:
-->Let us look at the level of the salt solution in beaker.
-->We find that, the level of salt solution in beaker is at the same level where we marked it for water.
---> this means that even after dissolving 50gms of salt in, 100 ml of water, the volume has not increased.
Conclusion:
This experiment tells us that , when salt is dissolved in water, its crystals separate into very fine particles.
---->These fine particles of salt go into the space between various particles of water due to which there is no change in volume and hence proved that there exist space between particles of matter.
