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…

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…

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…

Task-5 a) • Metals Metal structure is made up of crystals of metals which are made up of positive metal ions and these ions are surrounded by a sea of delocalized electrons. To separate these substances from this crystal lattice a lot of energy is needed. In between the positive and negative ions is present a strong electrostatic force of attraction. That is the reason why metals have strong melting and boiling points. In order to slide one layer of the metal ions over the other layer very less…

“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…

One of the challenges chemical engineers face with ethane cracking in a tubular reactor is the formation of a detrimental coke layer on the inner tube wall. According to the article [1], the mechanism is mainly induced by degradation of hydrocarbons to an aromatic structure by condensation and dehydrogenation. This brings about a bunch of various effects described in the article. In my model built during the term project, I decided to introduce a new effect of reducing the diameter, consider…

Metal plays a key role in development and it is the backbone for the manufacturing industry. For years, various metal have been extracted from the mineral ore found in nature, but with the time high grade ore have is getting depleted and the option at left with us is to processing low grade ore which makes recovery process expensive. In such scenario recycling metals seems a lucrative option as it helps environment by reducing the amount of scrap or waste material getting disposed into…

Due to regulations in the past, Farnsworth Paper Works, Inc., has an increasing buildup of fly ash on our property that has not been properly disposed. We would like to propose solutions to the Department of Natural Resources to allow us to receive permits to convert about half of our fly ash into low-grade fertilizer and to dispose of the rest of the unusable fly ash into the landfill on our property. Introduction Background Farnsworth Paper Works, Inc., which is regulated by the Department of…

Hardness Testing Lab 1 Moriah Ausherman E882U679 Kunza Arifa ME-251-10959 Thursday 3:30 Experiment Date- 8/31/2017 Due Date- 9/7/2017 Introduction: The purpose of this lab is to ascertain the hardness of two different materials. One material is aluminum the other will be determined through testing. Hardness is defined as a material’s ability to resist plastic deformation by indentation. Harder objects are more likely to resist deformation. The results of a hardness test will be…
