Solution
The correct option is C Iron
As we know lesser the force of attraction between particles more the distance between them and more the empty space in their molecules:
- Oxygen is a gas at room temperature. So, its particles have more space between them than a solid.
- Oil is a liquid. So, its particles have comparatively more space and less attraction between them, than a solid.
- Chalk piece can be easily broken because it's particles have weak forces of attraction than that of iron.
Hence, the correct order of empty space between the molecules is as follows:
Oxygen > Oil > Chalk > Iron
