and accurate measurements. The objectives in the experiment are to learn how to use laboratory equipment to determine volume‚ mass and temperature. It is also important to learn how to combine units to determine concentration and density in order to measure the density and concentration in different dilutions. Procedure Exercise 1 Length Measurements 1) Gather DVD or CD‚ key‚ spoon and fork. 2) Measure the length of each item in centimeters with one degree of uncertainty‚ record. 3) Measure

Archimedes’ & Pascal’s Principle Purpose In this lab‚ we will prove Archimedes’ Principle by finding the density of a Metal Cylinder‚ a cork‚ and an unknown fluid by using Archimedes’ Principle. We will also use the PASCO Pascal’s Principle Lab Setup to investigate the use of fluid pressure as a hydraulic system to do work and we will find its mechanical advantage. Procedure For the first part of the lab we will be verifying case 3 as explained by professor. We

8/11/14 The purpose of this lab is to calculate the density of aluminum with different masses and volumes of aluminum bits and water. Aluminum Bits balance graduated cylinder water cupcake liners paper towels 1. First‚ get materials ready for the experiment by cleaning and/or drying materials 2. Mass the cupcake liner 3. Add water to the graduated cylinder and record the volume of water added. 4. Place some aluminum pebbles into the cupcake liner and place it on the balance. Record

In this lab‚ there was a comparison between accuracy and precision of densities measured by volume. Mass measurements are often used units in the metric system. Volume can be examined a borrowed unit. The volume measurements were made in mL. Every measurement had a level of hesitancy affiliated with it. The experiment could feel uncertain from the object used for measurement and from the accuracy of the person doing the measuring of the volume. Because of this uncertainty‚ the experiment must be

There were several drops of the water cling to the beaker. This may increase the actual mass of water in each trial. In the density part‚ the mass and density of zinc electrode was measured and calculated to determine the accuracy of the measurement. The result shows that the densities of zinc electrode in two trials are 6.2±1.6 g/cm3 and 9.4±3.8 g/cm3 (The average density is 7.8±3.8 g/cm3)‚ which is not quite accurate‚ compared to the standard of solid zinc density1 (7.14 g/cm3)1.

calculating the mass and dividing it by the volume to get the density‚ then compare densities. 44. A student has several different-size samples of substances I and II. She measures the masses and volumes of these samples and plots the graphs shown in Figure D page 67. Which substance has greater density? How do you know? 2 2 more dense because it doesn’t rise as fast as number one. 45. How can you determine the density of ice? Can you determine the volume of the ice by melting it

reading h = 0.7 m‚ and depth L = 12 m. Q.2 (from Street‚ Watters‚ and Vennard) The weight density γ = ρg of water in the ocean may be calculated from the empirical relation γ = γo + K(h1/2)‚ in which h is the depth below the ocean surface‚ K a constant‚ and γo weight density at the ocean surface. Derive an expression for the pressure at any depth h in terms of γo‚ h and K. Calculate the weight density and pressure at a depth of 3.22 km‚ assuming γo = 10 kN/m3‚ h in meters‚ and K = 7.08 N/m7/2
