- A.
Rigidity.
- B.
Usability.
- C.
Ability to compress within its container.
- D.
Ability to conform to the shape of its container.
Correct Answer
D. Ability to conform to the shape of its container.Explanation
The correct answer is "ability to conform to the shape of its container." This is because liquids do not have a fixed shape and can take the shape of the container they are in. Unlike solids, liquids are not rigid and can flow and change shape easily. They have the ability to adapt and fill the space available to them, making them highly conformable to the shape of their container.Rate this question:
