Definitions of chemistry

  1. 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"
  2. the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactions
  3. 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. These atoms are not assumed to be indivisible, but merely the finest grade of subdivision hitherto attained. Chemistry deals with the changes in the composition and constitution of molecules. See Atom, Molecule.
  4. An application of chemical theory and method to the consideration of some particular subject; as, the chemistry of iron; the chemistry of indigo.
  5. A treatise on chemistry.
  6. The science which treats of the nature and composition of substances, and the laws which govern their relations.
  7. The science which treats of the properties of substances both elementary and compound, and of the laws of their combination and action one upon another.
  8. The science which treats of the composition and properties of bodies.
  9. That science which treats of matter considered as composed of atoms and of their relations and affinities.
  10. The science which treats of elementary bodies and their combinations, with the properties that distinguish and the laws that govern them. Inorganic chemistry, analysis of physical compounds; organic, analysis of vegetable and animal compounds. See Alehemy.
  11. The science that ascertains the nature and constituent parts of any body, investigates the laws that regulate the action of bodies on each other, and determines in what proportion their elements unite.
