>Weismann proposed the theory of continuity of germplasm, only the changes that affect the germ cells and the germplasm (the collection of genes) will be inherited by successive generations Darwin proposed the theory of natural selection to explain the 'survival of the fittest' to lead to the next ..

The first step in the manufacture of sodium carbonate is to generate carbon dioxide. This can be got by heating limestone. The Plant Used in the Solvay Process..

A magnet is moved over the mixture containing the magnetic substance e.g., iron filings. These get attracted to the magnet. The process is repeated until the magnetic material is completely separated from the mixture. Fig: 1.4 - Separation of a magnetic substance by a magn..

The clay is first washed with water in wash mill to remove the foreign materials. Powdered lime is added to clay and the mixture is finely ground and homogenised. The clay-lime slurry (40% water present) or the dry pulverized mixture (in the case of dry process) is introduced into..

The mixture is taken in a container and allowed to stand for sometime. The solid particles settle down with time. Settling down of the particles leaves the upper layers of the liquid clearer. Bigger particles settle down faster than the finer particles. Sometimes the sedimentation process..

The process of electrorefining of metals involves the following steps: The electrolyte is usually an aqueous solution of the salt of the metal with some corresponding acid, if necessary. A thick block of impure metal is made the anode. A thin rod/sheet of pure metal is made the c..

The process of electroplating involves the following steps: Before electroplating the metal surface is cleaned thoroughly. Firstly, an alkaline solution is used to remove grease and then it is treated with acid to remove any oxide layer. It is then washed with water. The article to ..

The Bessemer converter is turned into a horizontal position and molten pig iron is poured into it. A blast of hot air is sent through the tuyeres. The converter is rotated so that it is vertical and hot air is blown continuously. In its upward travel through the converter, the air oxidises the im..
