CHEM 130 Lecture Notes - Calipers, Propagation Of Uncertainty, Standard Ruler
Document Summary
The purpose of this experiment was to investigate if the composition of ten various cubes could be identified by calculating each respective density. During these calculations, uncertainty measures arose, which meant another goal of the experiment was to discern how to avoid mis- identifying the composition. To solve this issue and make the measurements as accurate as possible, an error propagation formula was used to properly classify each cube. Through this process, we were able to determine the material of seven of the cubes. The other 3 were unable to be identified because no perfect match was found in relation to their densities. The goal of this experiment was to understand how measurements can consist of errors, and how to deal with these uncertainties. To simulate this, we were given ten numbered cubes, and had to calculate the densities using two different tools. The ten cubes were measured with a vernier caliper and standard ruler.
