1-INTRODUCTION:- The increasing demand of electrical power in cities and industrial centres necessitates the installation of a compact and efficient distribution and transmission network. High voltage gas insulated switchgear (GIS) is ideal for such applications. The range of application of SF₆ Gas Insulated Switchgear extends from voltage ratings of 72.5 kV up to 800 kV with breaking currents of up to 63 kA‚ and in special cases up to 80 kA. Both small transformer substations and large load- centre

Internal Assessment Partners: Bhavya and Katherine Research question: Does the concentration (mol dm3) of sulphur dioxide in wine rise or fall when exposed to air for different time periods (0‚ 75‚150‚225‚ 300 minutes)? Purpose: Many adults enjoy the consumption of wine but are not aware of the different preservatives and chemicals that are added to the drink. Sulphur Dioxide‚ which is added to many food products including wine because it acts as a reductant‚ is ‘well known as a poisonous and

One of the items of food was banana chips‚ this product contains Sulphur Dioxide. According to H.A. Steinman‚ M le Roux and P.C. Potter‚ Sulphur Dioxide enhances a persons asthma. Only 4 items from the table contained preservatives whereas 6 did not. Not many fruits and vegetables contain preservatives simply because they come from nature. One of the items contained

CaCO3 (s) + 2HCl (aq) ----------- CaCl2 (aq) + CO2 (g) + H2O(l) AIM: The aim of this investigation is to experimentally determine the molar mass of carbon dioxide (CO2) by measuring its volume and calculating its mass. CO2 which we will measure will arise as a product of a chemical reaction between Calcium Carbonate (CaCO3) and Hydrochloric acid (HCl) as it is shown in the chemical equation above. Once we

The rich imagery in ‘Dulce et Decorum Est’‚ is a major reason why the poem is so powerful. In the first line‚ "Bent double‚ like old beggars under sacks‚" readers can see the weariness of the soldiers‚ trudging tiredly on the war ground. Also‚ by comparing them to beggars‚ the soldiers were probably very dirty after fighting for so long. Think of a soldier staying in a battlefield‚ their uniforms‚ their faces will most likely be covered with dust‚ grime‚ or even blood. In the second line

Thomas Newberg Chemical Weapons Convention Historically chemical weapons are rarely seen in combat but when they are they are used to great effect‚ killing thousands and injuring many more. Chemical weapons were first used in combat in May 1915 when the Germans released chlorine gas against the French in the Battle of Ypres. Over the course of WWI new chemical agents were developed including cyanide‚ phosgene and mustard gas. The Geneva Protocol of 1925 condemned chemical weapons but states that

Experiment 1: The Effects of Coal Mining Coal mining‚ particularly surface mining‚ leads to large areas of land being temporarily disturbed. The mine workings collect and conduct water that is in contact with the widespread pyrite‚ a mineral that produces iron and sulfuric acid when exposed to air and water. In this lab‚ you will see first-hand the reasons why mine drainage can be harmful to the local drainage system if left untreated. Materials: (3) 100 mL Beakers 1 tsp. Crushed pyrite 1 tsp. Activated
