The Hypothesis For The Lab Essay

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

The number of electrons forming a charge cloud around the nucleus is (pick one of the following) greater than; equal to; smaller than the number of protons in the nucleus of the atom.

1. View the three scenarios listed below. You must observe and analyze these as part of the lab.

To conduct your laboratory exercises, use the Laboratory Manual that is available in the classroom. Laboratory exercises on your CD may not be updated.

The sequence of steps to successfully obtain steel became known as the Bessemer process, and this would be responsible for the extremely fast innovation within society. This is very evident, as not only did steel acquire several different uses within society, but the effects had greater, beneficial impacts than anyone could imagine. The biggest use that steel was required for, was the building of railroad tracks. Thanks to this invention, the concept of transportation was redefined for people. Instead of wagons and walking, someone had the ability to now board a train, and reach their destination much faster than before. Along with the creation of the railroad system, the usage of steel also allowed society itself to become more advanced, as cities could grow bigger and more complex. Back when iron was used, the height of the building was extremely limited due to its fragility. However, now with the product of steel, architects were allowed to make buildings as high as they wanted, which led to the creation of the world’s first sky scraper in

Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water.

groups. It was conducted to further the research in choice overload and paralysis of the mind.

What is the goal of this lab? What question is it trying to answer, or what problem is it trying to explain?

This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.

Preparation is a key to success in this lab. For this reason, you are required to thoroughly read through the experiment information presented in the lab manual, and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab, I will not allow you to enter the lab and you will receive a zero.

* Coating material for manufacture of electrical steel from 7.5 per cent to 5 per cent

The materials used for the first part of the experiment comprised of the following: a microscope, 4 slides, 4 slide covers, blood samples, lancet, a sheet of paper towel, 3 test tube droppers, Solutions A, Solutions B, and Solution C.

In this experiment eight samples of 8620 steel were tested using heat treating, quenching, and tempering. One sample was normalized by heat treating, one was annealed by heat treating and oven cooling, one sample was water quenched, and the final five samples were oil quenched. Four of the oil quenched samples were tempered at the following temperatures: 1000°F, 1100°F, 1200°F, and 1300°F. Each sample underwent Rockwell Hardness testing and three Izod Impact Toughness Tests and the averaged results are shown in Figure 1

Steel products were defined by several attributes which determined the product application and defined quality. Grade described the metallic (chemical) composition of the steel, or the elements added to the basic recipe of iron and carbon to create the desired properties. Product described the shape of the product, including semi-finished shapes (blooms, billets and bars) and finished shapes (wires and coils). Surface finish described the smoothness and polish that could be applied to the material’s surface to enhance presentation. Size described the latitudinal and longitudinal dimensions of the product. Structural quality described the absence of breaks in the inner metallic structure. Surface quality described the absence of cracks or seams on the surface. Because specific applications called for specific attributes, many products were customized along one or more attributes for the customer. However, of all attributes, customers valued most the grade, which determined product performance.
