Chemistry 107 October 3, 2005 Experiment 7 Intermolecular Forces & The Evaporation of Liquids Summary: There were two parts to this experiment. Part A consisted of gathering two temperature probes and connecting them to the computer. The computer was opened up in Logger Pro to Experiment 7A. During this part, two chemicals were used. The first set of chemicals was ethanol and propanol. The temperature probes were immersed into these chemicals for 45 seconds. After 45 seconds, the computer was instructed to gather data while the probes were in the solution. After 15 seconds of being in the solution the probes were removed and the computer continued to gather data, while the probes were pointed towards the vent hoods. This process was repeated for the following chemical combinations: 1-butanol/n-pentane, methanol/n-hexane. Also for each of these trials, a graph was printed out to indicate the results from the experiment. Part B dealt vapor pressure at different intervals of degrees. In this section we were told to find the pressure

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
