Water poured from a narrow bottle into a wide bowl takes on a new outline. Which description matches a liquid?
ADefinite shape and definite volume
BDefinite volume but changing shape
CDefinite shape but changing volume
DChanging shape and changing volume
Answer & Solution
Correct answer: B. Definite volume but changing shape
1. A liquid keeps a definite volume, which is why the same amount of water fills the same space in either vessel.
2. Its shape changes to match whatever container holds it, so the outline in the bowl differs from the outline in the bottle.
3. A definite shape as well as a definite volume describes a solid.
4. Having neither a definite shape nor a definite volume describes a gas.
