In fundamental physics and classical material science, the four primary states of matter traditionally include solids, liquids, gasses, and plasmas, with solids characterized by their structural rigidity and resistance to changes in shape or volume. In a broader philosophical, historical, or alchemical context, the four classical elements were often associated with solid physical forms, while modern materials science frequently categorizes solid matter into crystalline solids, polycrystalline solids, amorphous solids, and quasicrystals based on their atomic and molecular arrangements.
