1. Longitudinal Round Tensile Test (ASTM E8) The purpose of ASTM E8 was to determine important properties of the metal specimens. The diameter and initial gage length were measure before the specimens were tested. The samples that underwent tensile loads were Cold Rolled Steel, 2024-T351 Aluminum, and Grey Cast Iron. The tensile test was carried out and when the specimen reached failure, its broken pieces were removed. Their failure diameter and final gage length were measured and recorded. From

When something is bent or snapped in half, you often notice that it can never go back to its normal state. My project is to show the difference in between snapping/ripping something in half, completely frozen and room temperature. I will be recording the way that different types of candy bars snap/rip in half frozen verses room temperature. There are two different types of deformation, elastic and plastic deformation. Elastic deformation is when the candy or material is “springy”. It also means

I. Introduction The purpose of this lab was to observe and record the bending stress and elastic properties multiple materials. A three-point bend is when a force is applied to the center of an object while it is supported on each side. This experiment was performed to record each material's flexural behavior so applications can be made with appropriate materials. The objective was to calculate the elastic modulus for each material tested. II. Methodology To start the lab, one measures and

dry ice is made from carbon dioxide gas. So in particular, it’s actually just solid blocks of carbon dioxide turning into a gas. Now that’s something! As far as we thought, it could have been just blocks of ice blown by a flamethrower. Then the carbon dioxide gas is pressurized and cooled until it forms liquid carbon dioxide. After that, it is injected into a block press in turn, turns the carbon dioxide liquid into a solid. Now that we understand what dry ice is, what is the other uses of dry ice

Melting points reported were determined in open capillary. The structures of the newly synthesized compounds were established using IR, 1H NMR, 13C NMR and LC-MS data. FT-IR Spectra was recorded on Jasco FT-IR Spectrometer, 1H NMR and 13C NMR were recorded in DMSO-d6 at 399.65 MHz and 100.40 MHz respectively. All the chemical shifts were reported in parts per million (ppm). LC-MS was recorded using Waters Alliance 2795 separations module and Waters Micromass LCT mass detector. Elemental analysis

Purpose: The purpose of performing the 2 gram lab was to obtain 2.00 grams of our solid product, barium sulfate. In order for barium sulfate to be a product, we decided to perform a double replacement reaction. Background: In order for barium sulfate to be a product, we decided to perform a double replacement reaction. A double replacement reaction occurs when two compounds with two elements in each compound combine. After they combine, the first element in the first compound combines with the second

The purpose of my experiment was to determine how the amount of salt affects the freezing point of water. My hypothesis was if I increase the amount of salt distributed in cups of water, then the freezing point of the water will decrease because salt dissolves in water while taking up volume simultaneously, which prevents water molecules from packing together and freezing. I tested my hypothesis by filling 16 nine ounce plastic cups with six ounces of water each. I then added one teaspoon of salt

In this experiment, we had an unknown sample from which we obtained a boiling point, IR (Infrared Spectroscopy) and H-NMR to determine the chemical structure of an unknown sample. To determine the boiling point of the unknown, we used a thiele tube with high-boiling oil inside. We inverted capillary tube in the small sample tube that was holding the liquid sample and gently started heating. We stopped heating after we could see a continuous stream of bubbles that were coming out of the capillary

Dry ice is a frozen carbon dioxide,a normal part of our earth’s atmosphere.Dry ice is a solid but turns into a gas which the term for this would be called sublimation.Sublimation occurs when the surface particles of a solid gains enough energy that they form a gas.Using dry ice is a way to keep the temperature low when a refrigerator is not available.People also use dry ice for projects and experiments. If you leave dry ice in a bowl at room temperature for several hours nothing would be left because

Introduction: In this assignment, I will be doing two experimentations on examining the impact of temperature on the Alka-Seltzer’s response time. The first experimentation that I will be doing involves some water that is room temperature. The second experimentation that I will be doing involves some water that is very hot. If I want to be able to figure out the impact of the temperature on water, I will have to document the time it will take for the Alka-Seltzer to go into solution. Materials:

Hydrogen atoms and one oxygen atom. The chemical symbol is H2O. Water is a odorless, colorless, and tasteless substance. There are three forms of water; liquid, solid, and gas. Heat is energy in the form of vibrating atoms. An ice cube is the solid form of water. Ice is colorless and odorless. Ice is a mineral, but it has to be in solid form to be qualified as a mineral. Because the molecules are locked in place, ice is hard and stiff.

If I add any other substance other than water the cornstarch will it still change into a solid-liquid matter? Colloids have the capability to change from a liquid to a solid by movement or even touch. Colloids often harden when they are being moved by if it’s in your hand it will turn into a liquid matter. According to("Science Activity: Is This Stuff a Liquid Or a Solid? | Exploratorium") l the main idea about this subject is to show how to make your own ooze. Isaac Newton identified the properties

RESEARCH REPORT Ice is the solid form of any liquid. A freezing point of a substances lowered by pressure. Most substances contract while frozen. Density of ice increase as the temperature of it rises. Molecules in solids are packed together very tightly in fixed positions. This makes it difficult for the solid to change shape. In liquids, molecules are close together but they can slide past one another and change places. Because of this, liquids can change shape easily. Ice was

two aqueous solutions of different ionic compounds were mixed? A double replacement reaction is a reaction between two aqueous compounds in which one component from each of the compounds exchange to form a precipitate. A precipitate is a resulting solid from the mixing of two aqueous compounds that react with each other. This experiment was performed to show the process of double replacement reactions and to explain when it experimentally occurs. To help display this, two aqueous solutions selected

Name: VISHAL KADU Assignment No.: 4 Unit Name: Properties and Applications of Engineering Material Unit No.: 19 Task 1: Describe the principles of the modes of failure known as ductile/brittle fracture, fatigue and creep. a) Ductile/ brittle fractures: brittle material breaks easily when heavy force is applied on it. Ceramics and cements are the best examples of brittle fracture. Ductile fracture is better than brittle fracture, because ductile fracture occurs over a period

The strategy recommended would match both external and internal fit that help Ice-Fili to increase its current market share (5%), maximise its long term profits and to achieve a sustainable competitive advantage. To dominate the Russian ice cream market and maintain its market leader position, it has to brand itself as the top historical Russian ice cream producer and strengthen its core product in the impulse segment. Due to little product differentiation, there is low brand loyalty for consumers

ice crystals from snow that is collected into one space. A solid, such as ice, contains particles that are not flowing freely and have their own defined space. All particles, even in solids, vibrate, but how fast they move depends on the amount of energy they have. That energy is measured in terms of temperature, or average kinetic energy, of the solid. When a solid is warm, its energy is greater and its particles move faster. When a solid is cold, the opposite is true,

In one of the experiments, the experimenter uses coke, lemonade, water, red party cups, and a thermometer. They put a measuring cup of each liquid into cups and they freeze them at 32 degrees Fahrenheit. The water froze the quickest, freezing within 2 hours. The Coke came second at 2 hours and 15 minutes. The lemonade froze the slowest at 2 hours and 35 minutes. The next site talks about how lakes, ponds, and puddles freeze in cold temperatures, but how the ocean doesn't. The reason for that is because

Sophia Vines Honors Chemistry Period 3 Group 1 September 30, 2016 Topic: Ice Melting Alternatives Background Research Since salt is an effective way to melt ice that is harmful to the environment, the objective of this experiment is to find a more eco-friendly alternative. For this experiment, the scientist will find out how effective sugar and fertilizer are at melting ice compared to table salt. The independent variable is the different de-icing agent (salt, sugar and fertilizer.) The dependent

Up in the clouds on a cold Winters day, water vapor condenses into a water droplet and freezes into a tiny specs of dust. The water molecules morph together as a hexagonal pattern. As the water vapor condenses on the surface and the ice crystal grows larger and small branches bud off the hexagonal ice design. The ice crystal grows heavy enough it falls to the ground and is called and is then called a snowflake. This process happens over and over millions of times during a snowstorm. They are formed
