Question
Which of the following is not a characteristic property of solids?
- Intermolecular distances between the particles are short.
- Intermolecular forces are weak.
- Constituent particles have at fixed positions.
- None of these
Hint:
Solids have densely packed molecules in their structure.
The correct answer is: Intermolecular forces are weak.
- The property that doesn't belong to solids is that their "Intermolecular forces are weak".
- Solids are those that do not have large intermolecular spaces. The molecules are densely packed, giving them a proper shape and structure.
- They are present so close preferably because of their strong intermolecular forces of attraction. Intermolecular forces of attraction refer to the forces between the molecules that hold them together. The stronger it is, the stronger the pull between them.
The strength of intermolecular forces of attraction decreases as we move from solids to gases.
