MEASUREMENT OF DENSITY Lichang Wu Feb. 22, 2015 Abstract The purpose of the lab was to determine densities of materials. Density is the amount of matter in a given amount of space. Density is a physical property that is independent of the amount of material present. The formula for density is density=mass/volume(d=m/v). Introduction Density is a measurement of the amount of mass that have a specific volume. Density is used for identifying substances. Density is reported as g/ml or
Discussion: Define and explain density in your own words. Density is calculated by dividing its mass by its volume (D=M/V). Density also describes how compact a substance is (amount of space occupied within a certain area). What is the difference between mass and density. The differences between mass and density are that mass is the amount of matter in an object and density is a measurement of how close the molecules are packed tightly together in a certain amount of space. In this lab, can
5861 Are these Objects Made of the Same Material? Every substance has its own unique density due to all of the atoms mass, size, and arrangement being different for each atom. Density is the relationship between two characteristics of matter which are mass and the occupied space. Density is a characteristic property, meaning the density of a substance will stay the same. In an investigation the objects densities would be calculated to determine whether the objects are made of the same material. The
had a density high than water and one that had a density lower than water. We found the densities of the spheres with one having a density above that of what, while the other sphere had a density below that of water. For this experiment, we were able to calculate both an experimental value and theoretical value for the densities of the two spheres, which is where our error occurred. The theoretical density of the heavy sphere was calculated to be 7893.9kg/m3, while the experimental density of the
a large role when creating a density column: density and buoyancy. A density column is a scientific experiment used to observe the density and the buoyancy of various objects and liquids. Density columns are created by layering different liquids in a clear graduated cylinder, each with a disparate density. Then, objects are dropped into the column, and based on their buoyancy, will either sink or float into each liquid. Also, since the liquids have different densities, they will not mix with each
Density is a key physical trait that all matter in the universe adheres too. Whether it’s the gravity of stars or the buoyancy of a beach ball, density plays a key role in how matter interacts with the laws of physics. Density is an intrinsic property, meaning that the amount of the substance does not affect its inherent value. By knowing this we know that certain elements or metals, all have different density’s and they can be identified by them. The purpose of this experiment is to identify two
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, and beaker
Introduction a. The purpose of this density lab was to show the different ways density can be measured. Density is the measure of mass in matter. To find density, you would have to find the mass and the volume of the object. Then the mass would have to be divided by the volume to find the density. Density and specific gravity are similar because specific gravity is the density of a substance in comparison to the density of the standard. In this case, the standard is the density of water. The correct number
24. For the purpose of this problem use 10 m/s 2 for g and 100000 N/m2 for 1 atm. What is the pressure at Point B? Your Answer: 8.5 atm Correct Answer: 9.0 atm Review the Examples in Chapter 10 in Giancoli. 25. Assuming that the density of air is a constant 1.3 kg/m3 and
The purpose of this experiment is to learn how to measure mass and volume and to determine the density of water, alcohol, and a solid. We will be using a laboratory scale or balance and the graduated cylinder to determine the density of water and of alcohol. First, place an empty graduated cylinder on a balance, determine its mass and record the value under the Density of Water: Data Table. Next, pour 25 mL of tap water into the graduated cylinder. Place the cylinder on the lab bench and read the
