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

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

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

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

Density: the compactness of a substance. That is the first thing that came to mind when I saw that diet coke floated in water and the cherry coke that sank in water. My group members and I measured the density of all three substances (diet coke, cherry coke, and water) and collected the data to see if density really was the cause. Based on our results, it turns out density really is the reasons diet floats and cherry sinks. After we collected our data from the lab, we did many calculations and found

Density: Using Experimental Techniques to Solve an Inquiry based problem ABSTRACT The topic of this experiment is Density. The objective is to find two ways in which the density of a given object can be determined, and to find out which of the two ways is more accurate and hence better to use in such a case. The two methods used in this experiment are finding the dimensions of the object and water displacement. These are two ways of finding the volume of an object, and they were chosen since

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

Title Page Density Formal Lab Report Name Professors Name Date Purpose/Objective: Determine density of a product for a plastic manufacturing facility. Provide quality control by making sure the physical properties are within design specifications. Density is defined as the ratio of an object’s mass to its volume, measured by dividing mass by volume (density = mass/volume). This was accomplished using two different experimental methods, displacement and floatation. The theory is that

The objective of this experiment is to find the density of metals through taking physical measurements and graphing data using the Vernier LoggerPro software. This was achieved through finding the mass and the volume of multiple samples of two types of metals and finding the average density of the samples of each type of metal, keeping record of the mass and volume of each sample, and inputting the data into the LoggerPro program. INTRODUCTION: Density is the mass per unit volume of a substance. It

The Density Den (Experiment 4.3) Taken from Obook (aim, materials and method) Date: Monday 15th June Partners: Nicole and Grace Introduction: - When people think of Archimedes they often think of the famous tale of his bath, and how he helped discover density whilst unknowingly using the displacement method. - Density is the mass and volume of substances which is different in the 3 states of matter. The density of the 3 matters can often be affiliated with the amount of space in-between the particles

Hypothesis The objective of the density determination lab is to determine/compare the average density of pre-1982 and post-1982 pennies. This can be achieved by finding the mass to volume ratio then averaging the results. The purpose of this lab is to find out if the difference in composition of the pre and post pennies will affect their densities. Pennies made before 1982 where majority copper but pennies minted after 1982 are made with mostly zinc. With this background knowledge, we expect the

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,
