Density

Density and SG by Hydrometer Method Objective The purpose of this practical is to determine the specific gravity and density of samples of methylated spirit of different concentrations, using a hydrometer. Introduction Theory Specific gravity (SG) is defined as the ratio between the density of a liquid to the density of water at a temperature of 4oC and pressure of 1 atm. It is of great importance when quoting the specific gravity of a substance to refer to the temperature and pressure at which

and Understanding Density, several experiments were performed to find density of regularly shaped objects, irregularly shaped objects, liquids and gasses. An additional experiment was done to find the specific gravity of a sampling of liquids. The purpose of the experiment was to provide a better understanding of density and to be able to extrapolate unknowns based upon these calculations. The experiments yielded data in keeping with Kinetic-molecular theory in regards to the density of water versus

Physics 141 Archimedes --1 ARCHIMEDES’ PRINCIPLE AND SPECIFIC DENSITY GOAL: To investigate buoyant force and Archimedes’ principle. To measure the specific density of several materials. INTRODUCTION: Try pushing down on a basketball in water and you feel the buoyant force that makes the ball float. As more of the ball is pushed beneath the water, the upward force becomes greater. One could make a first guess (Hypothesis #1) that the buoyant force increases with the submerged volume of the object

In this experiment, we will be testing density at different temperatures in a specific substance, in this case, sugar water. Density is the degree of the compactness of a substance. In your everyday life, density is all around even if you don’t realize it. To find density you have to divide mass by volume to get the density. Hypothesis If you heat up the sugar water at 30, 50, and 100 degrees celsius, the density will decrease. Procedure First, get a hot plate and scale, and plugged them in,

The density of water is its mass divided by its volume. In this case, the mass of water was determined by subtracting the final mass of the glassware with water by the initial mass of the glassware without water. The volume was determined by observing closely which line (marked on the sides of each glassware) the water reached and reporting the most precise measurement. Based on the class data, the average densities of water and its standard deviations were: 50-mL beaker – avg: 0.90 g/mL, stand dev:

The Relationship Between Density and Sugar Content Danielle Shaub Partners: Emily Alexander, Bill Dempsey, Shayla Ho Lab Performed 03/11/15 & Lab Report 04/07/15 Abstract: Using solutions of sugar and water alongside cola, density and percent sugar can be related. The purpose of this lab is to discover how and with what benefit these factors can be related. Using assorted measurements and the standard curve of the calculated densities and percentages of sugar solutions, it was learned that cola

The use of upper atmospheric density models is essential for orbit determination and geophysical research. This data plays an important role in understanding the exosphere, and can contribute to monitoring of next solar cycle. One of the major applications of studying upper atmospheric density models and their changes with the solar cycles is to track and identify active satellites as well as debris in the low earth orbit (LEO) and other higher orbits. Collision avoidance and reentry prediction for

to determine the density of a set of plastic beads by using two different methods and decide which method was better. Density is a physical property that is defined as the ratio of an object’s mass to an object’s volume. Also density can be described as the measurement of how compact a substance is in a given space. To find an object’s density, it is necessary to measure the object’s mass, the amount of matter present, and volume, the space it takes up. Also when studying density, it is important
