Matter exists in three main forms based on the arrangement of particles: solids have a definite shape and volume as particles are tightly packed in fixed positions; liquids have a definite volume but take the shape of their container as particles are loosely packed and free to move; gases have neither a definite shape nor volume as particles are spaced far apart and move freely in all directions.
