We have literally altered the chemistry of our planet's atmosphere If the supply of vitamins and minerals in the diet is inadequate, this will result in changes in body chemistry; 1: a science that deals with the composition, structure, and properties of substances and with the transformations that they undergo 2 a: the composition and chemical properties of a substance <the ~ of iron> b: chemical processes and phenomena (as of an organism) <blood ~> 3: a strong mutual attraction, attachment, or sympathy <they have a special ~>; a generic term used to refer to chemicals used in a darkroom; Once the goals for green products have been defined in terms of environmental test procedures and regulations, the next step is to understand the contribution that chemistry makes to toxicity; The study of substances What they are made of and how they work It is divided into three main branches -- physical chemistry, inorganic chemistry and organic chemistry; Chemistry is the scientific study of the structure of substances and of the way that they react with other substances; Relating to or using chemistry; An application of chemical theory and method to the consideration of some particular subject; as, the chemistry of iron; the chemistry of indigo; the scientific study of composition, structure, properties, and interaction of chemicals; Waste is heated above its ignition temperature in the presence of fuel and air to provide for complete combustion Time is allowed for the combustion reactions to proceed far enough to satisfy legal emission requirements; Chemistry deals with the changes in the composition and constitution of molecules; The study of the elements, the compounds they form, and the reactions they undergo Chemists try to discover new, useful compounds They do their work by using the results of experiments to prove their theories; The study of the elements, the compounds they form, and the reactions they undergo; "Chemistry? Yeah chemistry" is a line from Guys and Dolls A few friends and I have been trying to get it instituted as a Chelsea running gag, but without much luck; {i} study of the elements and compounds that can be made from them; emotional connection between people, suitability; A highly-scientific term describing the study of "stuff "; 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 mutual attraction between two people; rapport; An application of chemical theory and method to a particular substance; [kemistry] is from the Arabic kimia, whence al-kimia (the occult art), from kamai (to conceal) Inorganic chemistry is that branch of chemistry which is limited to metallic and non-metallic substances, which are not organised bodies Organic chemistry is devoted to organised bodies and their elements; the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactions; In photography and platemaking, a term that describes the composition of processing solutions; Chemical Acronym Database glossary menu; A treatise on chemistry; Everglades Florida Plants Herbs Scientific Journals Young Readers; If you say that there is chemistry between two people, you mean that is obvious they are attracted to each other or like each other very much. the extraordinary chemistry between Ingrid and Bogart. 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
