A blank has a definite volume but no shape of its own.

Understand the Problem

The question is asking about a state of matter that maintains a fixed volume but does not have a specific shape, which typically refers to a liquid.

More Information

Liquids maintain a constant volume because the molecules are close enough to retain a certain amount of volume but are able to move around freely, which allows them to take the shape of their container.

Tips

A common mistake is to confuse liquids with gases. Gases also lack a definite shape, but they do not have a definite volume either.
