The Copper A. In the text “the Copper” Glenn Gavin tells about his experience and viewpoints 20 months after he joined the Metropolitan Police. In the text are different subjects discussed. Glenn Gavin talks about his upraise inside the family and at school‚ the role of rules‚ his choice of carrier‚ and attitude toward politics. When Gavin was a kid his parents gave him a “guiding kick up the backside every now and then” (p. 1 l. 2). For example when he “came in late” (p. 1 l.3) or if he “was

equations‚ of copper and aluminium and describe the environmental impact of these extraction processes. Copper There are two main methods used to extract copper from its ores. Generally‚ copper is extracted using the Pyrometallurgical method (also known as smelting)‚ which allows us to separate copper from its sulfide and oxide ores; the other method‚ called the Hydrometallurgical method (also known as solvent extraction or electrowinning - SX/EW)‚ allows us to also separate copper from its oxide

Solder (/ˈsoʊldə/‚[1] /ˈsɒldə/[1] or in USA /ˈsɒdər/[2]) is a fusible metal alloy used to join together metal workpieces and having a melting point below that of the workpiece(s). Soft solder is typically thought of when solder or soldering is mentioned‚ with a typical melting range of 90 to 450 °C (190 to 840 °F).[3] It is commonly used in electronics‚ plumbing‚ and assembly of sheet metal parts. Manual soldering uses a soldering iron or soldering gun.Alloys that melt between 180 and 190 °C (360
