What is Chemistry?

Chemistry is a science that studies the composition, properties and changes that matter undergoes.

An expert in chemistry is called a chemist i.e. a scientist specialized in chemistry.

BRANCHES OF CHEMISTRY

Chemistry is divided into five main branches, which are:
1) Physical chemistry
2) Organic chemistry
3) Inorganic chemistry
4) Analytical chemistry
5) Biochemistry.

APPLICATION (IMPORTANCE/ CONTRIBUTION) OF CHEMISTRY IN THE DEVELOPMENT OF A MODERN SOCIETY

Chemistry plays a significant role in the development of a modern society. It has influenced most aspects of life including healthcare, energy production and environmental sustainability. Due to practical application of chemistry the quality of life for many people worldwide has improved. Most of the products that are obtained by the application of chemistry are useful for development of modern societies.

These products are processed in different areas such as agriculture, medicine, nutrition and cooking, manufacturing industries etc.

AGRICULTURE

Agriculture is a practice of growing crops and keeping animals. Farmers use many products made through chemistry knowledge to get better agriculture yields. These products include fertilizers, animal vaccines, pesticides, weed killers and processed animal feeds.

Fertilizers are used to improve the quality and quantity of crops.

Pesticides are used for destroying insects or other organisms harmful to plants. Pesticides are also used in animal dips to kill pests such as ticks that attack animals

Animal vaccines are used to protect animals from diseases and also to prevent transmission of diseases between domestic animals and human being.

MEDICINES

Medicines found in medical stores and pharmacies such as Panadol, coughing syrups, vaccines and food supplements are all made by application of chemistry. These materials ensure our well being through the treatment and prevention of diseases.

NUTRITION AND COOKING

Chemistry has an impact on the tastes, texture and nutritional value of food. Chemistry helps in understanding of different food components such as carbohydrates, proteins, fats and oils, vitamins and minerals. Chemical reactions involved in cooking help to have food that are healthy and palatable. For example, chemical processes are useful in the preparation of breads, cakes, rock buns and biscuits.
