States Of Matter Lab The States of Matter Lab was a very interesting lab for many reasons, one of them being the fact that we got to use Solid CO2. Most of the experiments revolved around the substance. Throughout our lab we had received consistent results. The lab helped us understand topics like Gas Density, Fluidity, and Surface Tension. We also had to draw particle diagrams for each experiment, which gave us a better understanding of the substances.
Percent Composition of a Penny Lab The Percent Composition of a Penny Lab was also interesting because we had to use an object that we see almost every day. I was not expecting the number that we got at the end of the lab, when we found out that only 5% of the penny is actually made out of Copper. We found this out by putting the penny into Hydrochloric acid.
