Chemistry in everyday life : Our entire universe is made up of matter which is constantly changing forms and evolving into other forms of energy. Chemistry is defined as the study or science of this ever changing matter. The other sciences which we study commonly like biology‚ physics and mathematics are all dependent on chemistry and are known as specific studies under the elaborate subject of chemistry. Since there is chemistry seen in biological forms as well as physical states of nature‚ there

Chemistry has been called the science of what things are. Its intent is the exploration of the nature of the materials that fabricate our physical environment‚ why they hold the different properties that depict them‚ how their atomic structure may be fathomed‚ and how they may be manipulated and changed. Although organic reactions have been conducted by man since the discovery of fire‚ the science of Organic chemistry did not develop until the turn of the eighteenth century‚ mainly in France at
