Which of the following is not a characteristic of a solid?
- AMolecules are closely packed
- BAbility to flow easily
- CFixed size
- DMore than one of the above
- ENone of the above
Show answer and explanation
Correct answer: (b) Ability to flow easily
Explanation
Solids have a fixed shape and volume and closely packed particles held firmly in place, so they do not flow.
Flowing easily is a property of fluids (liquids and gases), whose particles can move past one another.
