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

Manufacture of alloys for various industrial and general purposes is a rapidly growing aspect of chemistry.

Daily life
All through the day we are surrounded by hundreds of things that are in one way or another a product of chemical reactions. Soap, washing powder, preservatives, aerated drinks are all a result of many years of research that has been done in order to make our lives better.

Chemistry and Energy Resources

The energy resources of the world are mainly petroleum, coal, wood, nuclear fuels. To conserve the fast depleting reserves of coal and petroleum, attempts are being made by chemists to utilize alternate energy fuels. Nuclear energy, solar energy, ocean energy (hydrogen from seawater), which may provide inexhaustible sources, are being studied under chemistry for future energy needs.
Chemistry in Life Styles

In every walk of life, chemistry has been the pioneer contributor towards enabling the comfort, convenience and pleasures of man. Chemistry has helped us in getting a number of amenities. Some examples are: * Domestic requirements such as better fabrics, soaps, shampoos, cosmetics, dyes, oils, flavouring essences, paper etc.Air conditioning, refrigeration and domestic gadgets: To keep people cool and food fresh in all seasons, we make use of air conditioning. Chemical substances like liquid ammonia, liquid sulphur dioxide, CFC etc., are used in these machines. All consumer electronic
