What is Chemistry?

Definition of chemistry
Chemistry is the science, which deals with the composition and properties of matter, changes in matter and the laws or the principles which govern these changes. The discipline of chemistry is divided into different sub-disciplines, so that after getting basic knowledge of chemistry one can specialize in any discipline. This specialization facilitiates chemistry students to get higher education and do research work. It is not possible for any person to master himself with the science of chemistry. Therefore chemistry is divided into the follwoing branches.
1.  Physical Chemistry
It is the branch of t chemistry, which deals with the physical properties and physical behaviour of material things.
2.  Inorganic chemistry
The study of all elements and their compounds, except carbon is called inorganic chemistry

3. Organic chemistry
The branch of chemistry in which we study the compounds of carbon.
4.  Analytical Chemistry
  It is that branch of chemistry, which discusses the analytical methods for getting information about chemical compounds and chemical processes.
5.  Biochemistry
It is the study of chemical compounds present in living things.
6. Industrial Chemistry

The application of chemical knowledge in technology and industry and the preparation of industrial products is called industrial chemistry.

5.     Chemistry and the society

        Allah has created this universe with the greatest wisdom and skill and the creation of man is the biggest phenomenon of the universe. Allah has given man, the status of His deputy, in this universe. He has blessed him with superior capabilities, knowledge and a quest for investigation. Allah has given clear-cut instructions to study the mystery of the universe. We find in the Quran, for more than seven hundred times, Allah's behest to investigate the phenomena of Nature.
        Man has been investigating his environment since the beginning of his creation and has succeeded in collecting a lot of information about Nature. After processing this information, he has tried to unearth hidden secrets of Nature.
(Definition of Science)
        This search of man for collecting knowledge and integrating it, is called science.
    Science is the knowledge, with the help of which, man gets information about himself and his environment. He then thries to arrange this gathered information and explain the data thus compiled.
         The scientific knowledge is so vast that no one can understand and master it without classifying it in different disciplines. The major disciplines of science are chemistry, physics, biology (botany, zoology), geology and astronomy. There are no clear-cut boundaries of these disciplines. Scientists have done so, for their own convenience. As the universe is an integrated unit so its knowledge should also be an integrated one. How different disciplines of science are integrated can be seen.
