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

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

determined density that does not depend on its physical properties. In order to be sure, I would need to see that the density does not change when the amount of matter is changed. 2. In order to measure density, it is necessary to find both the mass and volume. 3. In order to conduct this experiment, a scale, a graduated cylinder, a micrometer, a ruler, water, and the actual elements will be needed. Purpose: The purpose of this density experiment is to determine whether density is an intensive property

Robert Boyle. He studied the change in volume and pressure of gases. In one of his experiments Boyle noticed "At a fixed temperature, the volume of a gas is inversely proportional to the pressure exerted by the gas."Boyle’s Law states that the volume of a gas varies with pressure assuming that temperature is constant. In simpler terms in Boyle’s Law volume and pressure are inverse or opposite of each other and temperature is constant. For instant if volume is up pressure will be down and vice versa

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

given unit volume. A physical property can be measured without changing the chemical identity of the substance. Since pure substances have unique density values, measuring the density of a substance can help identify that substance. Density is determined by dividing the mass of a substance by its volume. Density, volume, and mass have a clear relationship that can clearly be shown by the mathematical formula: Density= Mass/Volume In our experiment we used the determined mass and volume of the sample

would be calculated to determine whether the objects are made of the same material. The objects are all different colors, sizes, textures and shapes. In order to find density, the mass and volume would need to be calculated. In order to calculate the density of an object two things must be calculated the mass and volume of the object.

The purpose of this experiment, “Units of Measure - Weight, Volume and Length” is to become more acquainted with the different types of equipment such as pipettes, graduated cylinders, and more objects of that nature. The experiment concentrates on the measurement of objects using the metric system and relating it to scientific notation, significant figures, and more. A large component of the experiment revolves around the concept of ‘accuracy’ and ‘precision’, which is meant to be learned through
