From Wiktionary under the GNU Free Documentation License. Chemistry (from Arabic: كيمياء Latinized: chem (kēme), meaning "value") is the science of matter and the changes it undergoes. The science of matter is also addressed by physics, but while physics takes a more general and fundamental approach, chemistry is more specialized - concerned with the composition, behavior, structure, and properties of matter, as well as the changes it undergoes during chemical reactions. It is a physical science for studies of various atoms, molecules, crystals and other aggregates of matter whether in isolation or combination, which incorporates the concepts of energy and entropy in relation to the spontaneity of chemical processes. Modern chemistry evolved out of alchemy and began to develop into its modern form through the 10th Century Arab world and following the chemical revolution (1773). Disciplines within chemistry are traditionally grouped by the type of matter being studied or the kind of study. These include inorganic chemistry, the study of inorganic matter; organic chemistry, the study of organic matter; biochemistry, the study of substances found in biological organisms; physical chemistry, the energy related studies of chemical systems at macro, molecular and submolecular scales; analytical chemistry, the analysis of material samples to gain an understanding of their chemical composition and structure. Many more specialized disciplines have emerged in recent years, e.g. neurochemistry the chemical study of the nervous system (see subdisciplines). From Wikipedia under the
GNU Free Documentation License What is the amount of chemistry in the chemical engineering course? Q. I have applied for chemical engineering as my course in several universities. I am very interested in chemistry but I have heard that chemistry is very light in chemical engineering. Is that true? I mean, how light is "light"? Can someone give me a brief overview of the chemistry topics covered in the course? Asked by cc - Thu Apr 26 20:25:39 2007 - - 1 Answers - 0 Comments A. Chemical Engineering is a degree. Actually chemical engineering students have to take quite a bit of chemistry. The field of chemical engineering deals on how to design chemical plants to produce chemicals. Thus, a chemical engineer has to understand chemistry in order to design a chemical plant that is capable of producing tons of chemicals. Chemistry in the large scale is quite different than chemistry in small scale, since reactions, when a product is formed and if the reaction releases heat, the more product that is formed, the more heat is going to be released. Thus, a chemical engineer has to understand the process chemically and design a plant capable of dissipating all that heat without causing a fire, an explosion, etc. I… [cont.] Answered by William Q - Thu Apr 26 21:41:57 2007 What is the best chemistry book for a novice chemist? Q. I am a college graduate (BA) with little science background. I am interested in expanding my knowlege of chemistry, physics, astronomy - all of the exact sciences. I think chemistry is the best place to start a solid foundation. (If I am mistaken, I'm open to suggestions) What are some concise, yet readable books that I should choose? Asked by habaceeba - Tue May 16 17:53:27 2006 - - 2 Answers - 1 Comments A. To be honest, and I'm not insulting you in any way...But pick up "Chemistry for Dummies"...Or even "The Complete Idiots Guide to Chemistry". I'm telling you, when I had trouble with chemistry, these books spelled everything out clearly. They're rather inexpensive, as compared to some Chemistry text books you could buy online. The books helped me pass Chem 1 and 2 with straight A's. Now I'm on Organic 1 and these books still prove to be a wealth of information. Hope this helps...

Q. I have a project and i need to explain in 3-5 sentences that how is chemistry related to light bulb? I gave a thumb up to everyone who answered so thanks, i liked every single answer so its hard to decide which one is the best so i will have to let the people decide that.

If you bombard phosphors with ultraviolet light, they re-emit visible light. In normal operation, the fluorescent tube is connected to a source of electrical current. The current supplies electrons that slam around inside the tube. Inside the tube there is also mercury vapor. When electrons collide with the mercury vapor, they cause the vapor to emit ultraviolet light, which hits the phosphors and the tube lights up.
