Matter is a substance that makes up everything in the universe, having mass and occupying space by exhibiting volume. It is composed of atoms or the subatomic particles that constitute atoms: protons, neutrons, and electrons. Matter exists in various states, primarily solid, liquid, gas, and plasma, each distinguished by different physical properties and behaviors under various conditions of temperature and pressure. The interactions and combinations of atoms lead to the formation of molecules and compounds, which can exhibit a wide range of physical and chemical properties. Matter can change from one state to another through physical processes such as melting, freezing, vaporization, and condensation, or transform chemically through reactions that rearrange atomic connections. The study of matter is a fundamental aspect of physics and chemistry, providing insights into the composition, properties, and transformations of materials.
