with the help of an activity show particulate nature of matter
Answers
Answer:
Explanation
To demonstrate particle nature of matter
1. Take about 50 cm3 water in a 100 cm3 beaker.
2. Mark the level of water.
3. Add some sugar to the beaker and stir with the help of a glass rod.
4. Observe the change in water level.
Fig. 4.1. Dissolution of sugar in water. In solution particles of sugar are present in the spaces between particles of water
It is observed that the crystals of sugar disappear. The level of water remains unchanged. These observations can be explained by assuming that matter is made up of small particles. On dissolution, the particles of sugar get distributed into the spaces between particles of water.
• The constituent particles of matter are extremely small in size
The following activity demonstrates that the constituent particles of matter are very small
