Itzel Rodriguez Lab Summary 2A The main purpose of this lab was to observe the properties of water that are necessary for sustaining life. We were able to see how water molecules can surround ions and polar molecules. With the help of distilled water , slides, and pennies we were able to test different interactions between water molecules. With the glass slide we observed how bonds move from molecule to molecule. The results show that it is easier to move the slides with water but harder to break them apart. We were also able to see how intermolecular forces in the water molecules made a dome-like form on top of the penny, unless detergent was added. We also tested for surface tension with a beaker and a paperclip. We were able to see that the clip was not heavy enough to break the surface tension and that’s why it folated. We were able to see how the paperclip could float on water because its under the absolute surface tension. Thanks

    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.
