This is a solid.
Matter that has a uniform and unchanging composition is known as a substance. Substances can be classified into two main categories: elements, which consist of a single type of atom, and compounds, which are made up of two or more different types of atoms chemically bonded together. Unlike mixtures, substances have distinct properties and consistent chemical compositions.
A pure material is called a substance. It is a form of matter that has uniform and definite composition, with distinct physical and chemical properties.
A substance is any matter that has a fixed composition and definite properties. This means that substances are made up of specific elements in a certain ratio, and they exhibit unique characteristics that can be used to identify and describe them. Examples of substances include water (H2O), salt (NaCl), and oxygen (O2).
A chemical change involve a change of composition.
Several chemical properties can be estimated knowing the chemical composition.
It is a Substance
Matter with a definite chemical makeup is a pure substance.
Substance, classified as an element and compound. For an element, it cannot be separated into another simplier substance; for a compound, it can be dicomposed into elements using chemical processes.
Matter ( in any form) with a definite chemical composition . Also a umbrella term for drugs( substance abuse)

A chemical change involve a change of composition.
Fixed composition refers to a mixture where the components are present in a specific and unchanging ratio. This means the proportion of each component in the mixture remains constant regardless of the amount of the mixture present. Fixed composition is often found in chemical compounds where the elements are combined in a defined ratio.
