Volume One

using the volume and mass of an object can be used to the calculate density, and how the density can help you to identify what substance the object is made of. We began the lab by obtaining object C and recorded the physical properties of the substance. Next, the object was placed onto a scale to determine the mass in grams (56.56g). We used a ruler to measure the radius of the base (.6cm) and the height (5cm) of the cylinder-shaped substance. We plugged these measurements into the volume formula for

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

Density is the measurement of an object that has a relative mass and is divided by a specific volume. Mass is the amount of matter an object possesses. Volume is the amount of space of an object occupies (solid, liquid or gas.) In chemistry the term density can be described as a physical and intensive property of matter. The term intensive property means, it is independent on the size and amount of a substance. Many chemist compare different types of densities of elements and substance with water

density of each type of object and determining if calculating the volume, and therefore the density, of two cubes can be more effectively done with a ruler (through the direct method) or by water displacement.

Weigh and record the mass of each pair of objects (only use one rock when measuring the mass of the rock and use all four paper

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

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

quantification: measure by type vs. holistic measure 2.3.2.1 Flexibility measurement: measure by type 1. Volume flexibility Descriptive measure of volume flexibility can be the lower and upper bound of capacity for range dimension and time/cost of capacity adjustment for response perspective. But economic metrics are most commonly used in literature, since many researchers define volume flexibility as the ability to profitably produce at different levels. Stigler(1939) considered a plant to be

Fermentation is the anaerobic process by which glucose, or other sugars are catabolized by microorganisms without an electron transport chain, like yeast (Campbell, 2004). In experiment one the yeast and glucose acted as reactants, with the yeast breaking down the glucose, producing the products CO2 and ethanol. The overall reaction for the alcoholic fermentation that took place can be represented as 2 pyruvate + 2NADH-> 2NAD+ +2CO2 + 2 ethanol (Campbell, 2004). This biological process allows cells

Oil of density 0.8g/cm3 is poured in the other arm until the upper surfaces of the oil and glycerine are in the same horizontal level. Find the length of oil column. Density of mercury is 13.6 g/cm3.
