Prior to the lab, I proposed three questions in regards to density. The first question inquired which method of density calculation would be the most accurate. The second question asked if the sugar in the soda had an effect on its density. The third question stated what affect the varying size and shape of the copper pieces had on their density. These questions were explored in the experiment and some interesting conclusions were made at the end.
In the first half of the experiment, the density of copper is calculated using two different methods of measurement. The objective of the experiment was to compare the two techniques and decide which one was more accurate. The density of copper is 8.96 g/mL (Copper 1). The average density calculated by the class for the method using water displacement for the large rectangular block was 8.78 g/mL, a difference of .18 than the actual density amount. In comparison, those who used the caliper calculated the density to be, on average, 8.83 g/mL for the large rectangular block, a deviation of .13 from the actual amount. For the other copper pieces, the small rectangular block and small cylinder, the caliper calculated a density that was in close agreement to the actual density than the water displacement method. In addition, the deviation of the water displacement can be large, for example, the density that I calculated for large rectangle block was 12 g/mL, a difference of 3.04, which is a huge variance. Furthermore, the standard…
