Introduction to Chemistry

  Introduction to Chemistry Definition:-                 “The branch of science which deals with the study of composition, physical and chemical properties is called Chemistry.” Importance of Chemistry:-                 The importance of chemistry lies in the fact that we see different natural phenomena taking place in our environment. The process of rusting of iron, the formation of water, the formation of coal and all other things are studied under chemistry. Branches of Chemistry:-                 There are various branches of chemistry. Some of them are given below:- 1) Physical Chemistry:-                  “The branch of chemistry which deals with the study of physic...

Introduction to Physics

Introduction to Physics Definition:-                 “The branch of chemistry which deals with the study of matter, energy and their interaction is called Physics.” In other words, we can also say that in physics, we study about how a machine works, how everything in the universe is kept in orbit and how everything we see, came into existence. Importance:-                 The importance of physics lies in the fact that everything we see functioning is due to some principle of physics. The car washing centers use hydraulic press which works on the principle of Pascal’s Law . Similarly, some other examples can also be found in the working of other machines.        Branches of Physics:- 1)   Mechanics:-               ...

Introduction to Science

Introduction of Science Definition:-                 “When we perform some experiments then we obtain some observations and results. The knowledge obtained from that process called Science”. Origin:-                 The word “Science” is obtained from Latin Word “Scientia” meaning Knowledge.   Background:-                 When no particular information regarding the materials was known then all of these materials, which were known, whether they were Sun, Moon, Earth, the Minerals, Wood, Trees were studied under single subject called Natural Philosophy. But as the knowledge increased it was needed to divide into further studies. With this respect it was further divided into two parts:- 1) Physical Sciences:-       ...
