What is Chemistry and its Scope?
Chemistry is one of the important subjects in JEE Main entrance examination. There are three sections in Chemistry i.e. Inorganic Chemistry, Organic Chemistry and Physical Chemistry. Generally in examination, theoretical questions are asked from this subject. It is a branch of science dealing with the study structure, composition and properties of matter. Moreover, It also deals with the study of the changes with different forms of matter under different conditions.
Scope of Studying Chemistry
There are many examples in your day-to-day life that involve chemistry, its application, and its rules. Few of them are mentioned below:
- The Scope of Chemistry in Supply of Food- The study of chemistry has provided chemical fertilizers such as calcium superphosphate, Ammonium Sulphate, Sodium Nitrate, Urea. It has helped farmers to protect the crops from insects and harmful bacteria by the use of certain effective insecticides. Chemistry has led to the discovery of preservatives.
- The Scope of Chemistry in Industry- Chemistry plays an important and useful role in the development and growth of a number of industries. For example: Cement, glass, textile, leather,etc. It has also helped in the greater production of nitric acid, sulphuric acid,and Ammonia.
- The Scope of Chemistry in saving the environment- We have environment friendly chemicals because of Science which helps us to Conserve the natural environment. For Example Replacement of CFCs in the refrigerator.
