------------------------------------------------- Alloy Steel is a metal alloy whose major component is iron‚ with carbon content between 0.02% and 2.14% by mass. An alloy is a metallic solid solution composed of two or more elements. Complete solid solution alloys give single solid phase microstructure‚ while partial solutions give two or more phases that may or may not be homogeneous in distribution‚ depending on thermal (heat treatment) history. Alloys usually have different properties from those

m × c × ΔT. We can assume that the specific heat capacity of water is 4.18 J / (g × °C) and the density of water is 1.00 g/mL. The water has absorbed the heat of the metal. So‚ qwater = qmetal Using the formula qmetal = m × c × ΔT‚ calculate the specific heat of the metal. Use the data from your experiment for the metal in your calculation. Aluminum: q=26*4.18*6.3=684.684‚ c=q/(m*^T)=3.913 Zinc: q=26*4.18*10.3=1119.404‚ c=q/(m*^T)=2.608 Iron: q=26*4.18*7.8=847.704‚ c=q/(m*^T)=3.130

used for filtering rather than for boiling water. The material of kettle was then switched from iron to copper because it conducted heat more efficiently. It was one of the great metals and copper was a common of the 19th century. Cast Iron Kettle (3) Stovetop Kettle A stovetop kettle is a roughly pitcher shaped metal vessel use to fill water and boil water on a stovetop or hob. Sometimes stove-mounted kettles also have a steam whistle which indicates when the water has reached boiling point

bleach. Electrolysis is also used to extract reactive metals like aluminum and the purification of copper. [1][2] Electrolysis has many benefits like bleach. Bleach is usually used in cleaning household materials‚ and to whiten/lighten or clean stains on white cloth. Bleach is also used by ladies on their face to make their face white and bright. Other than that there is electroplating. Electroplating is the coating of a metal over the other metal. Electroplating is done for a few reasons to benefit

three types of groups; mainly metals‚ polymers and last but not least ceramics. Each and every type of the aforementioned group has their very own specialties‚ properties‚ structures and other characteristics. They all play an important role when it comes to selecting materials for the creation of a new equipment‚ device or product. Each group are observed or studied physically‚ mechanically‚ electrically‚ thermally‚ magnetically‚ optically and chemically. Metals are one or more metallic elements

In this lab we synthesized trans-[Bis(inosinato) palladium(II)] for IR analysis. After completion of the reaction 84.4% of the product was collected. IR spectrum of the product and inosine was analyzed to determine how the inosine is bonded to the metal‚ palladium. From the IR analysis‚ it was determined that when inosine reacts with palladium‚ a shift of about 65 cm-1 in the carbonyl stretch was observed. Introduction: In this experiment‚ trans-[Bis(inosinato)palladium(II)]‚ was synthesized
