SOME BA
Science can be viewed as a continuing human effort to systematise knowledge for describing and understanding nature. you have learnt in your previous classes that we come across diverse substances present in nature and changes in them in daily life. curd formation from milk, formation of vinegar from sugarcane juice on keeping for prolonged time and rusting of iron are some of the examples of changes which we come across many times. for the sake of convenience, science is sub-divided into various disciplines: chemistry, physics, biology, geology, etc. the branch of science that studies the preparation, properties, structure and reactions of material substances is called chemistry.DEVELOPMENT OF CHEMI
chemistry, as we understand it today, is not a very old discipline. chemistry was not studied for its own sake, rather it came up as a result of search for two interesting things: which would convert all baser metals e.g., iron and copper into gold. which would grant immortality. people in ancient india, already had the knowledge of modern science. they applied that knowledge in various walks of life. chemistry developed mainly in the form of alchemy and iatrochemistry during 1300-1600 ce. modern chemistry took shape in the 18 th century europe, after a few centuries of alchemical traditions which were introduced in europe by the arabs. after studying this unit, you will be able to D S S U H F L D W H W K H F R Q W U L E X W L R Q R I , Q G L D in the development of chemistry understand the role of chemistry in different spheres of life; H [ S O D L Q W K H F K D U D F W H U L V W L F V R I W K U H H states of matter; F O D V V L I \ G L I I H U H Q W V X E V W D Q F H V into elements, compounds and mixtures; X V H V F L H Q W L I L F Q R W D W L R Q V D Q G G H W H U P L Q H V L J Q L
