What do we call a form of matter that has a definite shape and volume?

A form of matter that has a definite shape and volume is classified as a solid. Solids are characterized by their closely packed particles, which are held together by strong intermolecular forces. This arrangement allows solids to maintain their shape and volume regardless of the container they are in, unlike liquids, which take the shape of their container but have a fixed volume, or gases, which neither have a fixed shape nor a fixed volume and will expand to fill their container. The term "sublimate" refers to the process of transitioning directly from a solid to a gas without passing through the liquid phase, and is not a type of matter. Therefore, solids uniquely possess the properties of both definite shape and definite volume.
