Question

State the approximate spacing between two molecules of a matter.

Answer 1

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:

1. In Solids:

   • Molecules are tightly packed.
   • Spacing: ~0.2 to 0.3 nm (very small).

2. In Liquids:

   • Molecules are loosely packed and can slide past each other.
   • Spacing: ~0.3 to 0.5 nm (slightly larger than solids).

3. In Gases:

   • Molecules are far apart and move freely.
   • Spacing: ~1 to 10 nm or more, depending on the pressure and temperature.
