Document Summary
Matter: anything that occupies space and has mass. Atom: the basic particles that compose ordinary matter. Molecule: atoms often bind together in specific geometrical arrangements to form this. Chemistry: the science that seeks to understand the properties of matter by studying the structure of the particles that compose it. State: classification of matter that depends on the relative positions of the particles and how strongly they interact with one another (relative to temperature) Composition: classification of matter that depends on the types of particle. Solid: particles attract one another strongly and pack close to each other in fixed locations; the particles vibrate but do not move around or past each other; has a fixed volume and rigid shape. Liquid: the particles pack closely, but slightly weaker attractions between the particles allow them to move relative to each other, giving them a fixed volume but not a fixed shape; they assume the shape of their container.
