The state of matter with no definite shape but a definite volume is a liquid.

Here's why:

* No definite shape: Liquids take the shape of their container. Think of water in a glass, a bottle, or a puddle.

* Definite volume: A liquid has a fixed volume, meaning it takes up a specific amount of space. For example, a liter of water will always be a liter of water, regardless of the container it's in.
