Science that deals with the properties, composition, and structure of substances (elements and compounds), the reactions and transformations they undergo, and the energy released or absorbed during those processes. Often called the "central science," chemistry is concerned with atoms as building blocks (rather than with the subatomic domain; see nuclear physics, quantum mechanics), with everything in the material world, and with all living things. Branches of chemistry include inorganic (see inorganic compound), organic (see organic compound), physical, and analytical (see analysis) chemistry; biochemistry; electrochemistry; and geochemistry. Chemical engineering (applied chemistry) uses the theoretical and experimental information obtained in chemistry to build chemical plants and make useful products; See Atom, Molecule; These atoms are not assumed to be indivisible, but merely the finest grade of subdivision hitherto attained; [3: chemical basis for life ]; the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactions the way two individuals relate to each other; "their chemistry was wrong from the beginning -- they hated each other"; "a mysterious alchemy brought them together; The study of the composition, structure, and other properties of substances and the transformations that they experience; The study of matter and its transformations See What is chemistry? for other definitions; The science which studies matter and how it changes; That branch of science which treats of the composition of substances, and of the changes which they undergo in consequence of alterations in the constitution of the molecules, which depend upon variations of the number, kind, or mode of arrangement, of the constituent atoms; scientific study of the composition, structure, and properties of substances and the changes they undergo; The branch of science that deals with the composition and constitution of substances and the changes that they undergo as a consequence of alterations in the constitution of their molecules; Chemical characteristics of surface water, particularly acidity and content of nutrients; chymistry
