Heavy metal contamination occurs though all facets of life such as air‚ water‚ food‚ soil‚ and in everyday objects and occurrences. When heavy metals enter the air from factories emissions and smoke‚ it is exposed to the body‚ which mostly affect your skin and lungs such as Cadmium and Arsenic. Common water contaminates are Chromium and Thallium‚ Chromium can enter the water source usually through spills and leaks from power plants. Thallium like other metals occurs naturally in water but some areas

Density of Metals Problem: How does the mass and volume help determine the density of known metal samples? Hypothesis: When comparing the density of Zn(zinc) and Cu(copper)‚ you will find that Copper is more dense than Zinc. You can test this out by using the density formula D=m/v. Materials: * 2 metals (options: zn‚ al‚ or cu) * 3 samples of each metal (small‚ medium‚ and large) * Scale/Balance * Calculator * Water * Graduated Cylinder Safety: * Be prepared for your

was able to design my own community service project. During 7th grade‚ I banded together with a few fellow classmates and we decided to clean up the streets of Felton one staple at a time. The state of the poles there were horrible; covered in the metal pieces from prior flyers posted there. After several weeks and hours‚ we had defeated the evil staples. In 8th grade‚ I had done some more community service on a smaller scale. By helping out in the community garden at school‚ I had helped the crops

The Metal Injection Moulding process (MIM)‚ considered as a development of the Powder Injection Moulding (PIM)‚ became‚ over the years‚ a competitive manufacturing process for small components‚ offering an alternative to other processes‚ more expensive to create these parts. History of the technology The PIM process was at first developed in the 1930s in the USA. This process was originally intended for ceramics. Then‚ during the Second World War‚ metal powders appeared. The process of Metal

Abstract This report is to highlight the methods‚ results and theory relevant during an engineering experiment called “cold rolling of metals". The purpose of this report is to show how readings obtained from the set-out experiment‚ can be evaluated to determine the behavior of 3 selected materials; Brass‚ Copper and Aluminium through the process of cold rolling. The form of the materials are in small strips which are processed via cold-rolling method 4 times from their original state to evaluate
