Discussion/Conclusion:

 

The goal of this lab was to explain Boyle's Law and Guy-Lussac's Law graphically. We were successful in achieving this goal. In the Data Collection section, Graph 1: absolute pressure vs. volume, accurately depicted Boyle's Law. As the volume increase, the pressure fell. This proved the inverse relationship between pressure and volume described in Boyle's Law. Graph 2: absolute pressure vs. inverse volume, also relates to Boyle's Law. As explained in the introduction, because the pressure and volume of a gas are inversely related, the equation p=K/T would depict a linear trend. Graph 3: pressure vs. temperature, ornaments Guy-Lussac's Law. This law states that pressure and temperature are directly proportional, and therefore when one increase, so does the other. Furthermore, a linear trend can also be observed here. Although the graph was somewhat turbulent occasionally, overall it reflected a straight shape. This fault could have arisen from the water not being heated up consistently. If there was not enough water in the bath or if the magnetic stirrer was not kept constant, the heating could have been erratic. Additionally, there could have been a small leakage in the rubber stopper. Based on the graphs produced in this lab, the results were fairly accurate in reflecting both Boyle's and Gay-Lussac's Law. In future labs, it would be crucial to stress the importance of evenly heating/stirring liquids and checking all equipment for damages in order to ensure accurate results. I would also increase the number of trials for this lab, in order to receive more vast and precise data. In conclusion, this lab was very successful and produced graphs that visually depicted how these two gas laws work.
