Describe a simple experiment to illustrate the existence of inter-molecular spacing.
Answers
Answer:
Take 100ml of water in a measuring cylinder. Add 20 grams of salt in water gently and stir it well so as to dissolve the salt well in water. It is noticed that the level of water does not change. It shows that the particles of salt occupy spaces between the particles of water.
Answer:
Requirements:
- 100mL of water
- 20g of salt
Procedure:
Pour the 100 mL of water into a measuring cylinder and mark the level of water. Then add the 20 grams of salt to it and stir.
Observation:
It is noticed that the level of water has not risen and is still 100 mL.
Conclusion:
This is because of inter-molecular spaces between the molecules of water due to which the particles of salt occupy those spaces, which results in no change in the water level. This proves the existence of inter-molecular spaces.
