Question
A solid has ________________.
- Definite shape, but no volume
- No shape, but definite volume
- Definite volume and definite shape
- No volume and no shape
Hint:
Solids are rigid.
The correct answer is: Definite volume and definite shape
- Shape and size depend on intermolecular forces of attraction and intermolecular space.
- In solids intermolecular forces of attraction are high and they have a rigid shape, particles are very closely packed and hence they have a definite volume.
- In liquids intermolecular forces of attraction are intermediate and liquids take up the shape of the container in which it is kept, intermolecular space is intermediate.
- In gases, intermolecular forces of attraction are negligible and intermolecular space is huge, they have no definite shape and volume.
