What term describes anything that occupies space and has weight?

The term that describes anything that occupies space and has weight is "matter." In scientific terms, matter includes all physical substances found in the universe, whether they are solid, liquid, or gas. It is defined by its tangible characteristics that can be observed and measured, making it essential in various fields of study, including cosmetology when discussing the products used and their properties.

While "element," "compound," and "particle" are related concepts, they do not encompass all types of matter in the same broad way. An element is a pure substance that cannot be broken down further and consists of only one type of atom, while a compound is a substance formed when two or more elements are chemically bonded together. A particle typically refers to a small localized object with physical characteristics, which may include atoms and molecules but does not define all matter comprehensively. Therefore, "matter" is the most appropriate term that covers all substances with mass and volume.
