Chapter i (1)
- 1. Importance of Chemistry to Daily Life
- 2. Chemistry • Chemistry is the study of matter energy , and the changes they undergo. • Chemistry is basic tool used extensively in the fields of ecology,agriculture,engineering,photography,metallurgy,nutrition, medici ne, dentistry and many others. • Chemistry is a body of systematized knowledge gained from observation, study and experimentation. By studying chemistry you will be able to understand the nature of the materials around you an the changes they undergo.
- 3. Role of Chemistry in Society and Industry Studying chemistry has many social benefits: •Food •Clothing •Building materials •Medicine That are the necessary in our daily life are products of the application of chemical knowledge. Many of the materials used in such fields as: •Architecture •Engineering •Nuclear science The results of the work of chemists. Without these and other innovations our ways of life would be radically different.
- 4. Contribution of Chemistry to Other Sciences • Chemistry involves a broad scope of both intellectual and experimental activities. Various opportunities exist for those who wish to pursue career in chemistry as a chemist, chemical engineer or chemical laboratory technician. • Chemical engineers are chemists with engineering training. They concerned usually with large scale industrial processes. • Biochemist are responsible for the research on the detection of the life span of living organisms that affect the body chemistry and the response to good health and nutrition.
- 5. • Industrial chemists provide information on the manufacture of construction materials such as plasters, synthetics, gravel and sand, cement wood, etc. • Environmental chemists take care of our environment while agricultural chemists are involved in the study of agricultural products like rice, corn, vegetables, meat poultry and livestock's. • Food chemists test food quality and also make chemicals that help food from spoiling.
- 6. Tasks of a Chemist • Research is an on- going process in all sciences. Because of chemical research will continue to make valuable contribution contributions to human progress. • Chemical research promises a brighter and productive future for all. To be a chemist is to be an architect of the future. • One of the major tasks of a chemist is using facts to build models or provide explanations to predict future observations • Another is testing models and explanations. Testing serves to confirm the validity of scientific concepts.
