Exploring Density Simulation Exploration: Login to the PHET Website. A basic property of any homogeneous substance is its density: the ratio of its mass to its volume. The density of a liquid or solid is an intensive property‚ which means that the density does not vary with the size of the sample but only depends upon its composition. The determination of density is a nondestructive physical process for distinguishing one substance from another. The mathematical relationship is: Density= massvolume

Title: Density‚ Alcohol Content and the Archimedes Principle (Performed 09/11/13) Report submitted by: Purpose: Part I was to examine three different objects of the same material in order to identify the type of metal. We used the water displacement method and the buoyancy method according to Archimedes Principle. Part II was to find the density of ethanol by mass. We used a 25.0mL graduated cylinder and a 25.00mL volumetric flask to measure the volume. We used two different pieces of glassware

packed closely together‚ but they are able to move around. Hence a fluid does not have a rigid shape‚ but adapts to the contours of the container that holds it. Like a liquid a gas has no fixed shape‚ but it has little resistance to compression because there is enough empty space for the molecules to move closer. Whereas a liquid placed in a container will form a puddle at the bottom of the container‚ a gas will expand to fill the container. Although the three categories seem very well defined

The density of fractions 1‚ 2‚ and 3 are as follows: 1.49‚ 1.325‚ and 1.34 g/mL. These values areincorrect because the density should not have been over 1.0 g/mL. This is because the density of water is 1.0 g/mL‚ and the product should have had a mixture of ethanol and water‚ making the density lower. The measured weight of the vials and ethanol were incorrect due the scales.There are many factors that can cause a scale not to read the correct value. The first is the airflow underneath the weighing

Expirement 1 Fluid Properties: Density and Surface Tension Table of Contents: OBJECTIVE 1 THEORY 2-3 PROCEDURE 4-6 RESULTS 7-8 DISCUSSION AND CONCLUSION 9 APPENDIX 10 OBJECT: The object of this experiment was to determine the density of a fluid by performing three different methods and use that determined density to calculate the surface tension of the fluid. THEORY: The density of any substance is defined as the mass per unit volume and is denoted by ρ. ρ = m / V (1) m is the mass

Matt R Results & Analysis Part 1: 1.) To determine the density and composition of a penny it must be first weighed on a scale. Find the average mass of multiple pennies from the same year. After weighing it find the volume by placing the pennies into a 50 ml beaker with 15 ml of water. Note the change in volume to obtain the volume of the pennies‚ obtain the average volume‚ and then calculate the density by dividing the mass of the penny by the volume. 2.) To keep measurements accurate and precise

Objective:- The aim of this experiment was to find the molar mass of unknown volatile liquid under known temperature and pressure. Introduction Molar mass or gram molar mass is the mass of the substance under consideration without distinguishing whether a substance is an element ‚ a molecule or an ionic compound. These elements‚ molecules or ionic compound could be solid gas or liquid. The molar mass of gas or vapor could be measured if the gases obey the law of Ideal Gas . The mass of

Determination of Cleansing Action of Detergents (Using Capillary rise) Synopsis This project report explains about the surface tension and capillarity of liquid through a simple experiment of finding the capillarity of various detergents. Oil stains and grease on dirty clothes cannot be removed‚ using water alone‚ because water does not wet them. If detergents added ‚ surface tension is decreased‚ the area of contact is increased
