What is the term used for matter that has a definite volume but no definite shape?

The term used for matter that has a definite volume but no definite shape is indeed liquid. Liquids have a fixed volume, which means they occupy a set amount of space. However, they do not have a distinct shape; instead, they take the shape of the container they are in. This characteristic allows liquids to flow and conform to the shape of their surroundings.

In contrast, solids have both a definite volume and a definite shape, maintaining their form regardless of the container. Gases, on the other hand, have neither a definite volume nor a definite shape, expanding to fill the entire volume of their container. Plasma, while also a state of matter, consists of ionized gases with unique properties, but like gases, it does not have a definite shape or volume. This understanding of the different states of matter is crucial in various electrical work contexts, such as understanding fluid dynamics in systems.
