Chemistry 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, being concerned with the composition, behavior (or reaction), structure, and properties of matter, as well as the changes it undergoes during chemical reactions. It is a physical science which studies various substances, atoms, molecules, crystals and other aggregates of matter whether in isolation or combination, and which incorporates the concepts of energy and entropy in relation to the spontaneity of chemical processes. Disciplines within chemistry are traditionally grouped by the type of matter being studied or the kind of study. These include inorganic chemistry, the study ofinorganic matter; organic chemistry, the study of organic (carbon based) matter; biochemistry, the study of substances found in biological organisms;physical chemistry, the study of chemical processes using physical concepts such as thermodynamics and quantum mechanics; and 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.
2011 was officially designated the "International Year of Chemistry" by the United Nations to commemorate the achievements of chemistry and its contributions to Mankind. I thought i would present my 1 Minute Take on the topic "Chemistry for Human Welfare."
"It is impossible to deny that Chemistry has played a major part in determining the nature of the modern world." - Linus Pauling, Double Nobel Laureate.
Chemistry is the study of Matter itself. The strides taken by Humans in the two millennia have a close connection with every science, Chemistry included.
Chemistry and human welfare are two interwoven aspects where both of them are complementary to...
