Lab Report Question- Why do few objects float in water where as others sink? Hypothesis- I think the objects that have a greater density than water will sink. So whichever object has a density more than 1g/cm³ will sink in water. This is known as relative density where the density of the substance is compared to the density of water. Hence, the object that has a greater mass: volume ratio than water will sink. Materials- * 1 measuring cylinder * 1 rectangular prism * 1 ball of...

• dENSITY - 314 Words
Research: The word density means the degree of compactness of a substance. There is density in everything in your everyday life (matter.)The formula to find density is d=m/v.The density of solids and liquids is usually stated as g/cm3, while gases are usually stated as kg/m3. A real life example of density would be that ice floats on water because it is less dense than water, or it sinks because it is more dense than water. The only substance that breaks this rule is ice.

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...

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...

Abstract This laboratory involved utilizing equipment to dilute a sugar water solution. It also created solutions containing varying levels of concentrations and densities. Equations were used to figure the molecular weight of the sugar, and the number of moles of sugar in the volumetric flask. There was also an equation to figure the Molarity, as well. As a result of the experiment, I now have a better understanding of the density of a concentration, and what Molarity is . Observations...

• Density Lab Report - 815 Words
Introduction: Density is defined by its mass per unit volume, and is most often written in mathematical terms as; d = m / v Mass is usually given in grams, g, and volume is given in cubic centimeters, g/cm3, or, grams per milliliter, g/mL. Density is not a property that depends upon the amount of substance present. For example, one gram of lead and one ton of lead have the same density. Density also does depend on temperature. For instance cold water is denser than warm...

INTRODUCTION 1.1 Background of the Experiment Mass density describes how heavy an object is. Defined by the Greek letter ρ, read as rho, density is a basic yet important physical property of matter. For a bulk body without accounting its existing pores and voids, density is represented by the ratio of its mass and volume. It is given by the equation ρ= massvolume 1. The SI unit of density is kg/m3. However, its CGS units, g/cm3 or g/ mL, are the most commonly used ones in the laboratory....
