उत्तर
INTER-MOLECULAR SPACES “The spacing between the molecules of the matter is called Inter-molecular spaces.”
The inter-molecular spaces in different states of matter:
- The intermolecular space between solids is absent.
- The intermolecular space between Liquid is moderate but present.
- The intermolecular space between gasses is free-flowing and plenty.
Explanation of inter-molecular space: Take water in a measuring cylinder say up to 80 ml. mark. Add 10 gm of salt to it. The volume in the cylinder should increase. On dissolving salt we find volume remains same i.e. up to 80 ml mark. This is because there are spaces in water molecules and salt molecules occupy these spaces and volume remains the same.
