Volume Three

In English 2111 we studied from the books of The Bedford Anthology of World Literature volume one through three. We as a class had to analyze three units; which were units 1 (Creation), 2 (Epic Heroes), and 3 (Courtly Love). Each unit had its level of difficulties but my favorite unit was unit 3 Courtly Love. Courtly Love gave me different outlook of love when I read the different poems and help me understand things I did not understand. To finish the summer strong we are to analyze once more taking

accurate and precise measurements while utilizing the correct volumetric containers that are used to quantify data. That way, all information that is collected can be trusted and accurately reflects the facts of the investigation. When measuring the volume of aqueous solutions, it is imperative to acknowledge the accuracy, precision, and percent error of the measurements. Accuracy is how close the results are to the actual accepted measurement, also known as the “true” value. Precision is how close

Determining the Density of a Polystyrene Sphere with Precision and Accuracy Abstract: The objective of the lab is to determine the volumes of the polystyrene spheres with three different measuring tools: Water Displacement, Analytical Scale, and Triple Beam Balance Scale. The experiment is meant to help understand the concept and application of precision and accuracy in experimental measurements. Accuracy is a measure of how closely the results of repeated measurements are to the true value of what

1. Objective: My objective for this experiment is to find the mass, volume, and density of a variety of objects. After this, I will record my data and place a select few of the items on a graph. My hypothesis for this experiment is, "If I measure the mass of every object, the wooden ball will have the least because it seems to be the smallest and most lightweight. " 2. Equipment: 3 rubber stoppers, 5 rocks, wooden ball, wooden cube, 4 density cubes, triple beam balance, graduated cylinder, pipette

to see if the three objects presented were made of the same material. The objects presented were a cylinder, cube, and a rectangular prism. Through examining the physical properties of the objects the best possibility in finding the substance of each object was through finding the density. Density is defined by a physical property between the mass and the space taken up by the substance. Density is found by using the formula mass divided by volume. Identifying the mass and the volume of each object

calculate the density of a solid or liquid sample, what measurements are needed? Mass and volume 3. The volume of a fixed mass of a liquid sample increases as the temperature rises from 20 to 408C. Does the density increase, decrease, or stay the same? Explain your answer. The density decreases. Density of the liquid sample is the mass divide by the volume. If the mass stays constant and the volume increases then the density of the liquid sample will decrease. 4. A solid block of exactly

Results and Conclusions: Density measures the mass of substance per unit of volume. Density of solids is measured in grams/cM3. Density of liquids is measured in grams/mL. Density of gases is measured in grams/Liter. Specific Gravity is when the density of many substances are compared are compared to the density of water which is 1 gram/cM3. If a substance has a density less than 1 gram/cM3, it will float but if the density is greater than 1 gram/cM3, it will sink

January 30, 2012 1. Title: Laboratory Techniques and Measurements 2. Purpose: The purpose of this lab is to learn laboratory techniques and to how to measure precisely. During this lab I will learn how to measure length, temperatures, volume, density, and mass using laboratory equipment. I will be using laboratory equipment to prepare dilutions and calculate them while using an algebraic formula. 3. Procedure: In order to perform this lab I needed the following materials: a metric

variable is the height of the water and the density of the water. Background Research How do objects float on water? The density and buoyancy are properties of matter that determine how objects float on water. Density shows the amount of mass in the volume of an object. For example, the density of water is one gram per cubic centimeter. It is a property that the quantity or shape does not affect the density of the material. This means that

Are the Volumes of Pure Substances Additive? Introduction In this lab, the densities and mass of water and isopropyl alcohol were calculated in order to answer the question ‘are the volumes of pure substances additive?’ This lab was used to help introduce the different types of glassware that will be used, as well as basic concepts such as density and the difference between accuracy and precision. Accuracy is how close the measure value is to the true value, while precision is how close the measured
