SCIENCE: CHEMISTRY Chemistry • the branch of science that deals with the identification of the substances of which matter is composed • the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances. • Branches of chemistry • Organic chemistry – concerned with the study of chemicals containing the element of carbon. • Inorganic chemistry – the study of all elements of compounds other than organic compounds. • Analytical chemistry – the study of qualitative and quantitative analysis of elements and compounds. • Physical chemistry – the study of the reaction rates, mechanisms, bonding, and structure. Matter • • Anything that has the property of occupying space and attributes of gravity and inertia. State of matter • Plasma – collection of charged gaseous particles containing nearly equal numbers of negative and positive ions. • Solid – characterized by resistance to any change in shape, caused by a strong attraction between the molecules of which it is composed. • Liquid – have sufficient molecular attraction to resist forces tending to change their volume. • Gas – molecules are widely dispersed and move freely, offers no resistance to change of shape and little resistance to change of volume. • Classification of matter
