Brief Historical Development and Contributions of Chemistry for Modern Civilization
Introduction: As defined by Oxford Dictionary, Chemistry is the scientific study of the structure of substances, how they react when combined or in contact with one another and how they behave under different conditions . In other words, Chemistry is the study of the materials and substances of the world in which we live. The materials, which make up the earth, sea and air, are called raw materials. These include many importance natural resources like ores, rocks, coal, and gas.
According to me, Chemistry is the study of the composition 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? Chemistry is the study of the 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.
Brief Historical Development: Chemistry plays an important part in all of the other natural sciences, basic and applied. From the earliest recorded times, humans have observed chemical changes and have speculated as to their causes. By following the history of these observations and speculations, the gradual evolution of the ideas and concepts that have led to the modern science of chemistry can be traced.
The first known chemical processes were carried out by the artisans of Mesopotamia, Egypt, and China. At first the smiths of these lands worked with native metals such as gold...
