Chemistry :-
The knowledge that provides understanding of this world and how it works, is
science. The branch of science which deals with the composition, structure, properties
and reactions of matter is called chemistry. It deals with every aspect of our life.
The development of science and technology has provided us a lot of facilities in
daily life. Imagine the role and importance of petrochemical products, medicines and
drugs, soap, detergents, paper, plastics, paints and pigments, insecticides, pesticides
which all are fruit of the efforts of chemists. The development of chemical industry has
also generated toxic wastes, contaminated water and polluted air around us. On the other
hand, chemistry also provides knowledge and techniques to improve our health and
environment and to explore and to conserve the natural resources.
Branches Of Chemistry :-
It is a fact that we live in the world of chemicals. We all depend upon different
living organisms which require water, oxygen or carbon dioxide for their survival.
Today chemistry has a wide scope in all aspects of life and is serving the humanity
day and night. Chemistry is divided into following main branches: physical
chemistry, organic chemistry, inorganic chemistry, biochemistry, industrial chemistry,
nuclear chemistry, environmental chemistry and analytical chemistry.
Physical Chemistry:-
Physical Chemistry is defined as the branch of chemistry that deals with the
relationship between the composition and physical properties of matter along with the
changes in them. The properties such as structure of atoms or formation of molecules
behavior of gases, liquids and solids and the study of the effect of temperature or
radiation on matter are studied under this branch.
