State the approximate spacing between two molecules of a matter.

उत्तर
The approximate spacing between two molecules of a matter depends on the state of matter (solid, liquid, or gas) and is typically measured in nanometers (nm).
Approximate Spacing Between Molecules:
-
In Solids:
- Molecules are tightly packed.
- Spacing: ~0.2 to 0.3 nm (very small).
-
In Liquids:
- Molecules are loosely packed and can slide past each other.
- Spacing: ~0.3 to 0.5 nm (slightly larger than solids).
-
In Gases:
- Molecules are far apart and move freely.
- Spacing: ~1 to 10 nm or more, depending on the pressure and temperature.
