Polyethylene Terephthalate Lab Report
This experiment was catalyzed by some Polyethylene Terephthalate (PET) bottle problems documented by the company. In order to prevent the loss of a customer, our goal is to analyze PET bottles, preforms, and storage conditions. After heating a bottle and preform to one-hundred and eighty degrees Celsius, the bottle shrank and became opaque on the top and bottom of the bottle. The preform became completely opaque and kept its original size and shape. The Differential Scanning Calorimeter (DSC) provided the heat of crystallization, heat of fusion, and glass transition temperature for PET bottle samples. The average glass transition temperatures for the top portion of an uncrystallized top and uncrystallized side are 80.605 +/- 1.1 Celsius and

    Polymers are large macromolecules composed of many small repeating subunits (monomers) connected via covalent bonds. Both natural and synthetic polymers are created via polymerization of these small molecules (Chemistry 144 Writing Assignment information sheet). The chosen polymer, polytetrafluoroethylene (PTFE) in the form of Teflon®, is a synthetic fluoropolymer of tetrafluoroethylene (Wikipedia, 2015), and is one of the most well-known brand names for PTFE based formulas, owned by DuPont Co.…

    What are the factors that lead to evolutionary change? Using mathematical equations, Hardy & Weinberg in the early 20th century showed that evolutionary change – measured as changes in allele frequencies in a population from one generation to the next – will not occur unless certain kinds of “evolutionary agents” are affecting the population. The Hardy-Weinberg equation can be used to describe the allele frequencies in populations that are not changing evolutionarily – and also can be used to determine if populations are changing over time.…

    When given two equations the goal is to make the equations equivalent to one another. These two equations are equivalent. Two equations are known to be equivalent if they have the same solution set. A solution set is a set of numbers that that solve an algebraic equation. In the first equation, the solution set is {5}. In the second solution set both sides of the equation must be equal. Equal means that both sides are balanced. The equality of addition property states that each side of the equal sign must have the exact same numerical value. On both sides, we have a which is the same “number” or “letter”. Since 5 is on one of the sides 5 must be on the other side due to the equality of addition property. That makes x {5}. Finally, because both of their solution sets are {5}, we know that the two equations are equivalent because they have the same solution set.…

    In the unknown identification labs, we have identified our unknown as Pseudomonas aeruginosa. Pseudomonas aeruginosa is Gram negative and rod shaped that we found to be motile in the lab. Our strain of P. aeruginosa formed colonies that were round in shape and had scalloped margins on nutrient agar. On our agar slant, the P. aeruginosa colonies had a filiform appearance on the edges.…

    Test Tube Mystery Lab Report

    The students were handed 10 test tubes with no identification. The students were supposed to design a method in determining what chemical was in each test tube. The list of chemicals is CuSO4, NH4Cl, NaOH, AgNO3, KI, H2SO4, NaBr, CaCl2, HCl, and Pb(NO3)2. The students are expected to determine the chemicals using physical properties, litmus paper, solubility, and the process of elimination. Physical properties, such as the color, can be determined by sight. Litmus paper can be determined through the change of color, if red then it is an acid, if blue then it is a base. Solubility can be determined through reacting two chemicals together and see if a precipitate is created. Previous knowledge of the solubility rules will help disclose whether two chemicals will or will not create a precipitate. When two chemicals do create a precipitate, it will be easy to determine which chemicals they are. In the end, one chemical will be left over.…

    Unknown Lab Report

    The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways, each was used in a way to help recognize those specifics and identify the unknown cultures. The differential tests used to identify the unknown cultures were oxidase, catalase, lactose and sucrose fermentation, Kugler/iron agar, nitrate reduction, gelatin hydrolysis, starch hydrolysis, manitol salt, MR-VP, citrate, bile esculin, indole, urease, DNase, and coagulase.…

    Pglo Lab Report

    The pGLO lab is a lab where students attempt to put the genes that make a jelly fish glow into E. Coli. After a process called transformation, the process in which a cell takes up and expresses a new piece of genetic information, the E. Coli will be able to glow and will be antibiotic resistant. The students first need to learn a couple of techniques before they are able to begin this lab. The first technique they will need is how to keep their environment sterile. They must learn to only open their tools, and other supplies for as long as they need, and keep them from touching anything. They must also learn that tools can never be shared between specimens, and when they use a tool, they should dispose of it and get a new one. Next they need to learn how to transfer a bacterial colony. To do this, one must use a sterile loop and scrape one colony off of the dish. Then they must insert the loop into…

    A&P lab report

    The primary function of the heart is to transport blood throughout the body, which delivers oxygen, nutrients and chemicals to the cells of the body to ensure their survival and proper function and to remove the cellular wastes. For the body to achieve this, it must maintain a certain blood pressure within the body to overcome gravity and orthostatic changes. If the body did not keep a certain pressure, distal cells and organs would not be able to receive a constant blood supply and cause a homeostatic imbalance. This experiment will show the possible changes in blood pressure due to gravity and orthostatic changes, but first, what is blood pressure and why is it important?…

    Pentane Lab Report

    By analyzing the data collected in the experiment and subsequently constructing graphs as shown above in figure 5 that plot the change of temperature against time with the inclusion of the different quantities of the isomer of pentane used. There are many kinds of trends which can be speculated about through analyzing the result graphs. Some of the different ways to identify trends within a graph, the main one being trend lines, the r2 value of the graph. A r2 value is a statistical measure of how close the data is related to all of the measurements found and how they fit on the regression line. The closer the r2 value is to the value of 1, the better the data fits on the regression line.…
