what are the different meanings of chemistry?

Answer 1

Definitions of chemistry on the Web:

* 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"

* Chemistry (in Greek: χημεία) is the science of matter and its interactions with energy and itself (see physics, biology). Because of the diversity of matter, which is mostly in the form of atoms, chemists often study how atoms interact to form molecules and how molecules interact with each other.

Answer 2

Chemistry [kem'-ihs-tree] is the science about chemical elements and compounds, and how these work together. It is the study of the materials that make up our bodies and everything in the world around us.

Chemistry began as a true science during the 1600s. This is when chemists discovered the simplest substances that make up all other substances. These simple substances are called elements. For a long time before that, people were trying to study these things to figure out how to do things like make gold, but no one ever did. This was called alchemy [all-kem-mee].

A chemical compound is a substance made up of two or more elements.

Answer 3

Chemistry usually means the study of chemicals but it can also be used to describe a class; I'm taking chemistry [the class] next year. The other meaning of chemistry is a sexual "spark" or compatibility between two people. For example, you might like someone because you have good chemistry together.

Answer 4

Chemistry (derived from alchemy) is the science of matter at or near the atomic scale. In this pursuit, chemistry deals with the structure and properties of such matter, the transformations of matter and the interactions of matter with other matter and with energy. Chemistry primarily studies atoms and collections of atoms such as molecules, crystals or metals that make up ordinary matter. According to modern chemistry it is the structure of matter at the atomic scale that is determinant of the nature of any given matter (See reductionism and quantum mechanics). It is, with physics, one of the most fundamental of all natural science

The other meaning is of the relationship between two people in love. We say the chemistry between them is very good.

Chemistry typically is divided into several major sub-disciplines. There are also several main cross-disciplinary and more specialized fields of chemistry.

Analytical chemistry is the analysis of material samples to gain an understanding of their chemical composition and structure. Analytical chemistry incorporates standardized experimental methods in chemistry. These methods may be used in all subdiciplines of chemistry, excluding purely theoretical chemistry.
Biochemistry is the study of the chemicals, chemical reactions and chemical interactions that take place in living organisms. Biochemistry and organic chemistry are closely related, as in medicinal chemistry. Biochemistry is also associated with molecular biology and genetics.
Inorganic chemistry is the study of the properties and reactions of inorganic compounds. The distinction between organic and inorganic disciplines is not absolute and there is much overlap, most importantly in the sub-discipline of organometallic chemistry.
Organic chemistry is the study of the structure, properties, composition, mechanisms, and reactions of organic compounds. In other words, it is the study of those substances that contain carbon.
Physical chemistry is the study of the physical and fundamental basis of chemical systems and processes. In particular, the energetics and dynamics of such systems and processes are of interest to physical chemists. Important areas of study include chemical thermodynamics, chemical kinetics, electrochemistry, statistical mechanics, and spectroscopy. Physical chemistry has large overlap with molecular physics. Physical chemistry involves the use of calculus in deriving equations. It is usually associated with quantum chemistry and theoretical chemistry.
Theoretical chemistry is the study of chemistry via fundamental theoretical reasoning (usually within mathematics or physics). In particular the application of quantum mechanics to chemistry is called quantum chemistry. Since the end of the second world war, the development of computers has allowed a systematic development of computational chemistry, which is the art of developing and applying computer programs for solving chemical problems. Theoretical chemistry has large overlap with (theoretical and experimental) condensed matter physics and molecular physics. Essentially from reductionism theoretical chemistry is just physics, just like fundamental biology is just chemistry and physics.
Nuclear chemistry is the study of how subatomic particles come together and make nuclei. Modern Transmutation is a large component of nuclear chemistry, and the table of nuclides is an important result and tool for this field.
Other fields include Astrochemistry, Atmospheric chemistry, Chemical Engineering, Chemo-informatics, Electrochemistry, Environmental chemistry, Geochemistry, Green chemistry, History of chemistry, Materials science, Medicinal chemistry, Molecular Biology, Molecular genetics, Nanotechnology, Organometallic chemistry, Petrochemistry, Pharmacology, Photochemistry, Phytochemistry, Polymer chemistry, Sonochemistry, Supramolecular chemistry, Surface chemistry, and Thermochemistry.
