What is Chemistry?

Answer 1

A Simple answer is: Chemistry is the science of matter and its changes.

If you are interested in more comprehensive definition, read on....



Webster's Dictionary says the following:

chem·is·try n., pl. -tries. 1. the science that systematically studies the composition, properties, and activity of organic and inorganic substances and various elementary forms of matter. 2. chemical properties, reactions, phenomena, etc.: the chemistry of carbon. 3. a. sympathetic understanding; rapport. b. sexual attraction. 4. the constituent elements of something; the chemistry of love. [1560-1600; earlier chymistry].
The first definition captures many of the essential ingredients of chemistry (although definitions 3 and 4 might make a more entertaining paper):

I. Chemistry is a SCIENCE. There is only one sanctioned procedure for determining whether a statement about matter is really chemistry: the exhaustive, inefficient, but highly successful scientific method. Chemists often arrive at new results by nonscientific means (like luck or sheer creativity), but their work isn't chemistry unless it can be reproduced and verified scientifically.

II. Chemistry is a SYSTEMATIC STUDY. Chemists have devised several good methods for solving problems and making observations. For example, analytical chemists often use protocols (thoroughly tested recipes) for determining the concentrations of substances in a sample. Chemists use well-defined techniques like spectroscopy and chromatography to study new or unknown substances.

III. Chemistry is THE STUDY OF THE COMPOSTION AND PROPERTIES OF MATTER. Chemistry answers questions like, "What kind of stuff is this sample made of? What does the sample look like on a molecular scale? How does the structure of the material determine its properties? How do the properties of the material change when I increase temperature, or pressure, or some other environmental variable?"

IV. Chemistry is THE STUDY OF REACTIVITY OF SUBSTANCES. One material can be changed into another by a chemical reaction. A complex substance can by made from simpler ones. Chemical compounds can break down into simpler substances. Fuels burn, food cooks, leaves turn in the fall, cells grow, medicines cure. Chemistry is concerned with the essential processes that make these changes happen.

V. Chemistry is the STUDY OF ORGANIC AND INORGANIC SUBSTANCES. Organic substances contain hydrogen combined with carbon; inorganic substances don't. It was once believed that organic compounds were exclusively produced by living things, but today chemists can synthesize many organic materials from inorganic ones. Carbon can link with itself and other atoms in many diverse ways, and its chemistry is far more complex than that of other elements. So while the organic/inorganic distinction is artificial, it's still useful.

VI. Chemistry is THE STUDY OF CONNECTIONS BETWEEN THE EVERYDAY WORLD AND THE MOLECULAR WORLD. Chemists use atoms and molecules to explain properties and behaviors of matter.

When you consider approximately the features located in a real "soul mate" dating, what one phrase comes up so much mainly at the most sensible of your record? Is it Chemistry? Probably. It is mainly defined as a sense that leaves you breathless, excited and vulnerable within the knees. Palms sweat, the center races and the frame tingles with frightened anticipation. The end so much could-be fanatics come to is if they revel in those severe emotions toward anybody, they have got the foundation for an perfect and lasting dating. Right? Maybe no longer. For this definition of chemistry is constrained to 1's bodily reaction to a different character. It lacks an whole size that is living in our values, ideals, personalities and worldview. In order to grasp you could have the proper reference to a competencies (or present) companion, it is main to have a elementary talents of what truly chemistry is composed of, that encompass it. This may also be tricky to do. This severe, bodily ardour is the stuff that Oscar successful films and satisfactory-promoting books are fabricated from. So, take a step again for a minute and notice for those who appreciate your self. :-)

Answer 3

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.

Chemistry is often called the central science because it connects other sciences, such as physics, material science, nanotechnology, biology and geology. Chemistry encompasses many specific specialized sub-disciplines that often overlap with significant portions of other sciences. Sub-disciplines, however, are very specific to chemistry, for example, they allow the manufacturing and testing of stronger materials, the synthesis of pharmaceuticals to treat disease, and determination of the mechanisms behind life processes.

Answer 5

# 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"
