Density Lab Report Abstract For the indirect determination of density of a pre-1985 penny, Archimedes’ displacement principle was utilized. When pennies were placed in the cylinder containing water, the increase in liquid level accounted for the displaced amount of water or the amount necessary to evaluate the density of the penny given the mass of a couple of pennies for each of five recorded sets…

At this stage, given the mass, it may be hypothesized that the mass of pennies divided by the volume displaced or occupied which causes rise in the water level within the graduated cylinder yields to the penny’s density. Methods and Materials Type of Metal Used: Early-1985 penny with an accepted density value of 7.18 g/ml. Initially, a 50-ml graduated cylinder was filled with 20.00 ml of water, and it was carefully recorded. The initial mass of cylinder and water (combined) was acquired using a top-loading balance and then recorded as initial reading for the cylinder-balance setup. Pennies were dropped by increments of two where the new volume was read and the new mass was measured using the same balancing equipment each time. This step was carried out repetitively to make a total of five data sets, which includes noting of final volumes along and masses (7th and 8th columns) through addition of previous differences with actual volumes and masses, correspondingly. There were ten pennies dropped all in all, and in order to obtain the experimental value of density for each set of pennies, the following equation was applied: Density, ? = [ Mass(2) - Mass(1) ] / [ Volume(2) - Volume(1) ] (in g/ml) Results Initial Volume of Water (ml): 20.0 ml_ Initial Mass of Cylinder + Water: 105.06 g_ density, g/ml % difference Rep A 5.03 29.94 Rep B 9.82 36.77 Rep C 10.06 40.11 Rep D 5.00 30.36 Rep E 9.98 39.00 Sample Calculations (using Reps A & B of the table): Actual Volume = 21.5 ml - 21.0 ml = 0.5 ml Actual Mass = 115.0 g - 110.09 g = 4.91 g Density = Actual Mass / Actual Volume = 4.91 g / 0.5 ml = 9.82 g/ml Final Volume = Actual V1 + Actual V2 = 1.0 ml + 0.5 ml = 1.5 ml Final Mass = Actual M1 + Actual M2 = 5.03 g + 4.91 g = 9.94 g Then using the given theoretical value = 7.18 g/ml and the formula % difference = | 9.82 - 7.18 | / 7.18 x 100% = 36.77% volume, ml mass, g 20 105.06 21 110.09 21.5 115 22 120.03 23 125.03 23.5 130.02 Based on the 3rd and 4th columns of the first table, beginning with a volume (water) of 20.0 ml and a mass (cylinder + water) of 105.06 g, the amounts (volume and mass) of each succeeding row are subtracted from the corresponding amounts of the preceding row to generate the 5th and 6th column outputs showing actual entries specific for every two-penny increment. Since these densities appear to be significantly different as compared to the literature value of 7.18 g/ml, the average density was estimated from the graph of mass vs. volume of pennies. Considering the best-fit line drawn (via MS Excel program) fairly between the plotted coordinates, the slope would be 7.186 g/ml according to the resulting equation m = 7.186v – 39.36, so that percent difference equals (7.186 - 7.18) / 7.18 x 100% or 0.0836%, which is appreciably lower than the % difference solved individually, as shown prior. Discussion / Conclusion Though the outcomes reflect inconsistent values of density on the basis of the actual volumes and actual masses which had been arrived at through the displacement method, ...Download file to see next pagesRead More

Determining the density of an irregular solid
...? Determining the density of an irregular solid Steve Beckman WGU INT1 December 12, Determining Density of an Irregular Solid 0 Problem ment Challenge to the determination of the density of an irregular solid is poised to its non-conformity to the any three-dimensional object that are used in the functional determination of the volume of natural and synthetic three dimensional objects. An irregular object falls outside the circular, ellipse, triangular, square, and rectangular or sphere basic units used in the mathematical computation of object. From the microscopic point of view, any material usually has a specific arrangement of its atoms. The bonding between the atoms determines the strength of the material. Due to uniformity... in the...

...Specific gravity The specific gravity of two liquid samples was measured using a hydrometer. The specific gravity measured was accounted in the buoyancy of each liquid relative to water. Specific gravity was calculated by dividing the density of each liquid sample by the density of the standard substance, distilled water in this case. Goals The aim of the experiment was to determine the specific gravity of two liquids using a hydrometer. Introduction: The specific gravity of a substance, represented by Gs, is defined as the ratio of the density of that substance to the density of distilled water at a particular temperature (40 C). The value of Gs is a numerical value...

...Density Lab Conclusion Data Interpretation Density Lab is conducted for the purpose of determining densities of different substances after which the experimental data collected are compared to the densities of these substances found in literature. For one, the pine’s density as obtained in the experiment is 0.47 g/ml which falls within the theoretical range of 0.35 – 0.67 depending on the class of pine (which in this case is near the value of kind radiata at 0.48). Similarly, the experimental density of oak which is 0.75 g/ml is well within 0.6 – 0.9 and closest to the true values 0.74, 0.77, and 0.74 which are densities...

... Theory 1 Explain the physical principle of the tools for: a. SP log The Spontaneous Potential log is sensitive to electrical charge. In this same regard, it functions by measuring electrical potentials between depths in oil boreholes together with a voltage exhibited on the surface. Hydrocarbon suppression reduces the response which can be realized by the SP log. b. GR log The Gamma Ray log uses gamma radiation to measure the characteristics of rocks or sediments in a well. It functions well even in steel or concrete walls because of it being sensitive. c. Density log This type of log is majorly attributed to its sensitivity to porosity. This is the property which enables it to function the way it does. It is able to determine... the...

Error Propagation: Volumes Linearized plot: Density
... Error Propagation and Graph Linearization in Volumes and Density Introduction In lab experiments, errors emerge from numerous sources including variability of instruments, imprecision in observation and sample differences among others. Errors typically increase when the number of variables involved increases. In order to determine the average value of errors encountered, a thorough error propagation exercise is necessary. Error propagation entails combination of individual uncertainties as a means of determining the accurate value of an experimental error. Aside from error propagation, lab experiments also benefits from the concept of graph linearization. In most cases, a pair of variables under analysis may portray a non-linear... of mass...

Archimedes Principle
...Lab Report on Archimedes’ Principle Theoretically, density, or rather specific density of parent material determines whether an object sinks or floats when immersed in water. Specific gravity is the ration of a material’s density to that of water. Practically, the physical properties of volume, density, and mass are related as d = m/v. Experiments that study the floating and sinking properties of different materials are practical application of Archimedes Principle (Smith 15). According to the principle, volume of liquid displaced when an object is immersed in water is directly related to the weight of the immersed object. Below are tabulated results indicating numerous...
