MCQ
A liquid can easily change its shape but a solid can not because.
  • A
    The density of a liquid is smaller than that of a solid.
  • ✓
    The forces between the molecules is stronger in solid than in liquids.
  • C
    The atoms combine to form bigger molecules in a solid.
  • D
    The average separation between the molecules is larger in solids.
✓

Answer

Correct option: B.
The forces between the molecules is stronger in solid than in liquids.
The forces between the particles of a solid are stronger than those between the particles of a liquid, so the particles cannot move freely but can only vibrate. Thus, a solid has stable, definite shape and volume. A solid can only change its shape by force (when broken or cut), whereas a liquid can easily change its shape because of weak inter-particle forces.
