Magnesium Magnesium has the symbol Mg from the greek word magnesia a district of Thessaly, sir Humphrey davy in 1755. Atomic number 12, atomic mass 24.31, 12 electrons, 12 neutrons. Physical properties: magnesium is a shiny, silver or grey coloured metal that is light in weight and strong the density of magnesium is 1.738 g/ml (1). Melting point 650◦C, boiling point 1090◦C (2). This image shows what magnesium This image shows the crystal Metal looks like 2) structure of magnesium 2) Polyvinyl Chloride Polyvinyl chloride is one of the most used polymers in the world. Due to its versatile nature PVC is used extensively across a broad range of industrial, technical and everyday applications …show more content…

The mechanical properties of metals determine the range of usefulness of a material and establish the service life that can be expected. Mechanical properties are also used to help classify and identify material. The most common properties considered are strength, ductility, hardness, impact resistance, and fracture toughness (10). mechanical properties are used in engineering by using a load test to see what the wait is for a job that your on or if you need a 2 tone weight and you make one up so you use the load test to see the weight of it and how much more you need to put on it. You also use material in engineering such as stainless steel and carbon steel. Stainless steel is used because of its high corrosion resistance, high ductility, high strength and hardness and also high hot strength. Carbon steel is also popular in engineering because of its corrosion resistance, hot strength, ductility, high strength and work …show more content…

Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others (11). Physical properties are used in copper wire because copper wire transfers heat from on end to the other but it still consists of copper at every point. Thermal Properties Every material used in an envelope assembly has fundamental physical properties that determine their energy performance like conductivity, resistance, and thermal mass. Understanding these intrinsic properties will help you chose the right materials to manage heat flows (12). In the real world you would use thermal properties for cooking such as using a frying pan to boil an egg or some other food that can be cooked in a
