without metal. The metals we use in our houses are mostly for keeping them sturdy. Though there is one problem we have when it comes to metals. That problem is that they rust. Metals rust when they are in contact with oxygen‚ and water. They rust much faster when they are in contact with salt water‚ and acid rain. We chose to see what would happen to various metals when they contacted with salt water. When the electrons move around in the salt water‚ it causes the metals to rust. The metals we chose

Density of Metals Lab 1. Purpose The purpose of this lab was answered in 4 questions‚ and their answers are here shown. The density of the metals we used were 5g/cm3. The density of a metal piece does not depend on its size‚ it depends on the total mass and total volume. The most accurate way of determining density is dividing mass by volume. You can’t identify metals by their density. It can help you narrow the options down‚ but you can’t identify a metal by using only its density. 2. Question

Metal detectors in schools pose more of a threat than a sense of security. Every student carries metal of some form on them. Pens‚ pencils‚ notebooks and other school supplies all contain metals. If we try to make schools “safer” by placing metal detectors in the entrance and exit of every school building. With many school shootings and stabbings‚ media and parents have proposed new safety measures. Placing metal detectors and spending extra time on safety management takes time away from class and

renovation‚ most people don;t think about it much before it is time to get a new roof. However‚ there are many great alternatives to asphalt shingles‚ and metal roofing is an option that stands out. Of course‚ when imagining a metal roof‚ the first thing that comes to the many people’s minds is a warehouse or other commercial structure. Metal roofing has come a long way and is so much more fashionable that its reputation‚ and is even being used on high-end mansions.

Ankit Shingala Dr. Campagnolo Chemistry H September 24‚ 2013 Lab on Density of Four Metals Conclusion In this lab we studied the densities of four different metals using a caliper‚ a digital scale‚ and a calculator. Three metals were pure elements like copper‚ iron‚ and aluminum. The fourth metal was an alloy which was brass. The purposes of this lab were to demonstrate that different metal elements have different densities‚ and that alloys have densities somewhere between those elements that

more bonus if they’re doing a quality job as well as getting the work done quicker than others. The last but not least‚ Gillette Metal did not seem to have policies discouraging workers from leaving early or sleep in warehouse during working hour. So Employees in Walt feels free to do such behavior. How should it be done? First‚ retiming the jobs in Gillette Metal by experienced employees‚ such as Vern and Bud so that Walt will know the actual working hours for each job. Second‚ reset piece rate

DRAWING AND ITS PROCESSES Drawing is a metalworking process which uses tensile forces to stretch metal. It is broken up into two types: sheet metal drawing and wire‚ bar‚ and tube drawing. The specific definition for sheet metal drawing is that it involves plastic deformation over a curved axis. For wire‚ bar‚ and tube drawing the starting stock is drawn through a die to reduce its diameter and increase its length. Drawing is usually done at room temperature‚ thus classified a cold working process

I.Case Analysis Overview Cumberland Metal Industries (CMI) is one of the largest metal manufacturers in the world. The company evolved from selling metal as a finished product to one that used it as a raw material‚ increasing sales from $250‚000 in 1963 to over $18‚500‚000 in 1979. Currently‚ CMI relies heavily on SlipSeal‚ which is used as a high-temperature sealant in automobiles. Although CMI dominates the market for this product‚ corporate sales figures decreased over the last year. As a

Specific Heat of a Metal Post-Lab I. Purpose The purpose of this lab is to determine the specific heat of an unknown metal. II. Safety Wear goggles and lab apron at all times. Use caution when boiling water. Do not pick up hot beaker or hot metal with hands. Use tongs. III. Pre-Lab Questions 1. A 12.5 g metal is raised to 100C in boiling water. It is put into 82.8 g of water at 22.4C‚ and the water rises to 28.6C. Recalling that the specific heat of water is 4.18J/gC‚ use the equation above
