 Electric discharge in gases Electrical discharge through gases is studied by using a specially designed glass tube commonly called as a discharge tube. It consists of a cylindrical glass tube having a side tube, and two metallic electrodes one at each end. These electrodes can be connected to the respective terminals of a … Read more Electric Discharge In Gases

 Endothermic Reactions Endothermic reactions are those chemical reactions where energy is absorbed by the system from the surroundings mostly in the form of heat. The concept is applied in the physical sciences like chemical reactions where hear is converted to chemical bond energy by way of experiments. Common examples of endothermic … Read more Exothermic And Endothermic Reactions.

  

   QUICK REVISION ( ARTICLE:3, SCIENCE): TYPE OF NUCLEAR REACTORS   COMPONENTS OF NUCLEAR REACTOR:   Fuel: Usually pellets of uranium oxide (UO2) arranged in tubes to form fuel rods. The rods are arranged into fuel assemblies in the reactor core   • Moderator: This is material which slows down the neutrons released … Read more Type Of Nuclear Reactors

 Rubbers There are many different kinds of rubber, but they all fall into two broad types: natural rubber (latex—grown from plants) and synthetic rubber (made artificially in a chemical plant or laboratory). Commercially, the most important synthetic rubbers are styrene butadiene (SBR), polyacrylics, and polyvinyl acetate (PVA); other kinds include polyvinyl chloride (PVC), … Read more Rubbers

 Chromosomes Chromosome, the microscopic threadlike part of the cell that carries hereditary information in the form of genes. A defining feature of any chromosome is its compactness. For instance, the 46 chromosomes found in human cells have a combined length of 200 nm (1 nm = 10− 9 metre); if the chromosomes were … Read more Chromosomes

 Introduction and application of genetic engineering Genetic engineering Genetic engineering, the artificial manipulation, modification, and recombination of DNA or other nucleic acid molecules in order to modify an organism or population of organisms. The term genetic engineering initially referred to various techniques used for the modification or manipulation of organisms through the processes … Read more Introduction And Application Of Genetic Engineering

 Electric current Ohm’s law and Resistance   Electrical current is the flow of charged particles. The flow of charges will be constant in current electricity. Electric current flows from higher electric potential to lower electric potential. For the current to flow, it requires a circuit which is closed loop of a conducting material. … Read more Ohms And Resistance
