A liquid can readily change its shape while a solid cannot, because
A liquid can readily change its shape while a solid cannot, because
Options
- Athe average distance between molecules is greater in solids
- Batoms combine to produce larger molecules in a solid
- Cthe forces between molecules are stronger in solids than in liquids
- Dthe density of a liquid is lower than that of a solid
Correct answer
C. the forces between molecules are stronger in solids than in liquids
Step-by-step solution
In solids, the intermolecular forces of attraction are very strong, which holds the constituent particles in fixed positions and restricts their movement. This gives solids a definite shape and rigidity.
In liquids, the intermolecular forces are weaker compared to solids. This allows the molecules to slide over one another, enabling the liquid to flow and readily change its shape to take the shape of the container.
