Metallurgical Processes - The process of extracting a metal from its ore and refining it, is called metallurgical process or simply as metallurgy. The actual process of extraction of a metal from its ore depends upon the nature of the ore and the metal. There..

Isothermal process is that in which the temperature of the system remains constant. Adiabatic process is where there is no exchange of heat between the system and the surrounding. Isobaric process is when the pressure on the system remains constant during any ope..

A manufacturer makes two models A and B of a product, each to be processed by two machines. To complete one unit of model A, machines I and II must work 1 hour and 2 hours respectively. To complete one unit of model B, machines I and II must work 4 hours and 2 hours respectively. Machine ..

This gene is located adjacent to the operator gene. It has two functions. 1.The promoter gene marks the site at which the RNA polymerase enzyme binds. When the operator gene is turned on, the enzyme moves over the operator gene to reach the structural genes and the tr..

Action of Heat on Substances - Heat is a very powerful form of energy. Although there are other forms of energy like light and electricity, heat is the most commonly used agent for initiating all chemical changes. Various classes of substances undergo decomposition to various extents when heated. T..

The growth of plants is regulated by certain chemical substances, which are synthesized by the plant in very small quantities. These substances are formed in one tissue or organ of the plant and are then transported to other sites where they produce specific effects on growth and development. They ..

Conservation of wild life has three objectives a) To maintain essential ecological processes and life supporting systems. b) To preserve the diversity of species or the range of genetic material found in the world's organisms. c) To ensure sustainable utilisation of species and ecosystem..

Titration is an operation for the measurement of quantities of substances in solution by the method of 'volume analysis'. This process involves adding a solution of the reagent of known concentration (standard solution), taken in a burette (called 'titrant'), to an unknown..

A heat engine takes heat from a hot body, converts a part of it into work and rejects the rest to a cold body. A refrigerator also known as a heat pump, does the reverse operation. It takes an amount of heat Q 2 from a cold body, an amount of work W is done on it by the surrounding and th..
