Document Summary
Chemistry: study of the composition, properties, and structure of matter. Molecules: atoms that are chemically bonded to each other. Particles are held in place in a ridged arrangement. Particles are close together but free to move around. Particles are far apart and independent of one another. Vaporization: molecules escape from liquid to gas phase. Fusion (melting): molecules move from solid to liquid. Freezing: liquid loses ability to flow, becoming solid. Sublimation: molecules escape from solid to gas phase. Properties of matter: determined by the properties of the particles that make up the matter. Matter may go through both physical and chemical changes depending on conditions. All matter is composed of tiny, indestructible building blocks called atoms. Idea originated in greece around 5th c bc. No evidence for the existence of atoms until much later= philosophy. Concise and generally applicable statement or equation that expresses a fundamental scientific principle. Chemical change requires bond breaking and bond forming.
