Density

Abstract

This experiment was conducted in order to determine the density of the Aluminum metal samples provided in the lab. Specific tools such as the vernier caliper and balance scale were used to measure and record the values found. Given that density is a measurement of mass over volume, both of these quantities would have to be determined experimentally, prior to proceeding with the calculation of the density, for each of the six subjects tested. Being as accurate and precise as possible, the data yielded a density that was similar to that of the accepted value for the density of aluminum. Taking averages of the measurements recorded by both partners may have introduced a variable for error. However, upon calculating the percent error of the results found, it was concluded that there was less than a three
The volume was then calculated using the formula to calculate the volume of a cylinder. The diameter and height measurements were taken using the vernier caliper. As shown below, the vernier caliper is an effective tool that can be used to help measure the diameter and height of objects accurately. Adjusting the jaws and turning the screw clap appropriately until the jaws were securely fastened around either the diameter, or the height of the object was the apparatus used to properly obtain the measurements needed. This procedure can be quite meticulous and due to its delicate and sensitive nature, may easily introduce error into the measurements, ultimately effecting the integrity of the results from the experiment. Nonetheless, the utilization of this technique would ultimately assist in determining the volume by providing accurate measurements to insert into the appropriate
