Preface

Chemistry is the study of matter and energy and the interactions between them. Chemistry tends to focus on the properties of substances and the interactions between different types of matter, particularly reactions that involve electrons.

Because understanding chemistry helps you to understand the world around you. Cooking is chemistry. Everything you can touch or taste or smell is a chemical. When you study chemistry, you come to understand a bit about how things work. Chemistry isn't secret knowledge, useless to anyone but a scientist. It's the explanation for everyday things, like why laundry detergent works better in hot water or how baking soda works or why not all pain relievers work equally well on a headache. If you know some chemistry, you can make educated choices about everyday products that you use.

Chemistry affects all aspects of life and chemists are therefore involved in tackling major problems of scientific and social concern. It plays an important part in many fields of technology, so that graduate chemists must be familiar with a variety of facts, figures, theories, experimental and instrumental techniques. Its concepts and problem solving opportunities, and its laboratory activates train hand and mind. These and its relation to other sciences from physics to medicine, and its role throughout technology means that graduate chemists have an especially wide choice of career.

You could use chemistry in most fields, but it's commonly seen in the sciences and in medicine. Chemists, physicists, biologists, and engineers study chemistry. Doctors, nurses, pharmacists and veterinarians all take chemistry courses

 

 

Chemistry

• The branch of science that deals with the properties of substances and the reactions that transform them into other substances.

• Chemistry is a central science.

• Chemistry uses the scientific method to advance its knowledge.
