With an help of an activity demonstrate that particles of matter are continuously moving
There are several examples and activities that show particles of matter are continuously moving. Few of them are:
Aim - To demonstrate that particles of matter are continuously moving
Apparatus - Beaker , water , and potassium permanganate crystals
Procedure -
(i) Take a beaker and fill it with 100 ml of water
(ii) Add 5 gm of potassium permanganate crystals to water.
(iii) Observe the changes.
Observation -
When potassium permanganate is added to water slowly the color of water changes to pink as both the particles of water and potassium permanganate are moving , hence they are mixed without stirring.
Conclusion - This mixing of potassium permanganate without stirring into water shows that particles of matter moves continuously.
2. Place a bottle containing concentrated aqueous solution of ammonia in a corner of the room. Remove the stopper.
It is observed that ammoniacal smell can be sensed sitting at a distance.
It demonstrates that the particles of ammonia are moving. Due to this motion they are able to reach the observer.
Similarly, if an incense stick is lighted and placed in one comer of a room, its pleasant smell spreads in the whole room quickly. It demonstrates that the particles of matter possess motion. A burning incense stick produces some gases (vapour) having pleasant smell. The particles of these gases due to motion spread in the entire room and their presence can be felt by sensing the smell.
3. Aim -To demonstrate motion of particles in water and ink:
Materials required - Beaker , water , blue ink
Method
1. Take a 250 cm3 beaker and add about 100 cm3 of water to it.
2. Put a drop of blue ink to the water taken in the beaker.
Observation -
It is observed that the blue ink gets evenly distributed in the water.
Conclusion -
This demonstrates that the particles of water and ink possess motion.
Due to motion of the particles, the particles of the two liquids are able to mix with each other.
