Ductile iron pipe

Part 1: Test of Melting Point Generally, ionic solids have very high melting point temperatures. Covalent molecules have a lower melting point. Polar covalent molecules have a higher melting point than non-polar covalent molecules. 1. Mold an aluminum foil boat that will serve as a tray for the table salt, sugar, wax. 2. At different corners of the boat place a very small amount of each substance. a. Table Salt b. Sugar c. Wax 3. Set the hot plate on high. 4. Observe and record the order…

Mineralization is independent of igneous processes. Host rocks comprise two types: calcareous or dolomitic siltstone, shale, and carbonate rocks of marine or lacustrine origin; and non marine sandstone, arkose, and conglomerate. In addition, the iron oxide copper-gold and basaltic copper deposit sub models may be applicable within some of the areas studied. Deposits of the reduced-facies subtype (model 30b.1; Cox and others, 2003), also termed coppershale or stratiform copper deposits, are…

Ceramics material are compounds between metallic and non-metallic elements where it most frequently oxides, nitrides, and carbides(William D.callister,JR, David G. Rethwisch,2015). This material use for technical applications are commonly based on aluminium oxide. The properties of ceramics which are insulative to the passage of heat and electricity and more resistant to high temperature and harsh environment(William D.callister,JR, David G. Rethwisch,2015). Ceramics in cochlear implants use for…

When heat is applied to an object, that object usually undergoes a structural change. This also applies to rock. Since Knife River Flint is a fine-grained stone the changes predictably would be minor, compared to a coarse-gained stone that would exhibit greater change when it came to thermal altering. Ahler purposed “that fine-grained cherts respond to heat alteration at lower temperatures than do coarse-grained cherts” (Ahler 1983: 2) which Knife River Flint is a fine-grained chert, so it…

molecules themselves in the skin. And in some countries it is still used as scalpels in hospitals. Later Steel became the main use for spear heads, forging a spear head although was not easy. It would start with some high carbon, low carbon, and pure iron into a crucible, that was capped off with a clay cap, completely sealed from oxygen. Then is put on the bottom base of the smelting forge, the forge is thus ignited and supplied consistently for 5-8 hours…

First Mineral: My first mineral of choice is Titanium. Titanium is a metal that was discovered in 1791 by William Gregor. A few common properties are its low density, inflexibility, resistant to extreme temperature, and corrosion. Ti is titanium chemical formula. Titanium is vital in my everyday uses for instance my newly purchased wallet, Apple laptop that I use for school and the golf cart I drive around the park. Dentist use titanium for patients who receive teeth implants. Titanium powder…

When the atoms of the molecules collide, heat energy is produced/released. More atoms colliding, make more energy to release. Therefore, metals are very good conductors of heat. 4. Malleability and Ductility: -Malleable- To be beaten into sheets -Ductile- To be drawn into…

In this experiment, I tested the effect of saltwater on the formation of rust on an iron nail. To test this, The first step was to fill each labeled cup with the correct ratio of salt to water. The ratios varied between groups which created different concentrations of salt for the different groups thereby constructing different levels of my independent variable. The next step was to record the initial mass of each nail and then place them in the cups. Then, the nails were left to soak in their…

Iron is an essential mineral that is needed for oxygen transport in the body’s blood and muscles. It is a major component in making hemoglobin in red blood cells and myoglobin in muscles. Hemoglobin and myoglobin are two proteins that transport oxygen from the lungs to the body’s muscles via blood. Iron also plays a role in energy metabolism. During exercise, iron aids the body by converting carbohydrates into energy and supplying the muscles with fresh oxygen. There are two forms of iron, heme…

“From the dawn of mankind, metals have fascinated man in many ways. From simple items found in the fire to advances in forming metals into trinkets, jewels, to weapons.” (A History of Welding). Welding is a profession that has been around since the dawn of the use of metals. The art of welding has changed the way we make things, and how we are able to build massive structures that stand taller than mountains. Well, this art form is called welding, and I believe it would suit me very well as a…
