Chemistry is the branch of science which studies the characteristics of substances and the changes they undergo when they are mixed one with another. Chemistry uses this new information to prepare new substances of value to us. Chemistry is involved in some way with almost everything we do or use. It is central to most of science and technology, blending at one extreme into physics, mathematics and engineering and at the other into the earth and life sciences. Chemists are employed in industries which provide us with food, energy, consumer goods, in regulatory bodies that protect our health and environment and in research institutions that provide new materials and techniques for the future. In other words, chemistry is an essential part of modern life. It also supplies us with the answers to many questions, such as - * Is this food fit for consumption?

* How can we make stronger fibers?
* How can we design a new fuel cell?
* How can we make pharmaceutical, or vitamins?
