Dec 3, 2025 · For detailed treatments of the properties, states, and behavior of bulk matter, see solid, liquid, and gas as well as specific forms and types such as crystal and metal.

Jul 20, 2025 · The four states of matter—solid, liquid, gas, and plasma—are all fundamental concepts in science. Each state has unique properties based on how particles are arranged and how they move.

Matter can be classified into two broad categories: pure substances and mixtures. A pure substance is a form of matter that has a constant composition and properties that are constant throughout the sample.
