onto the end of the syringe connecting the end of the syringe to the other end of the small piece of plastic tubing. Then the plunger was adjusted so there would be 60.0mL of air in the syringe. The quick-release connector on the end of the plastic tubing with the pressure port of the absolute pressure sensor was aligned. The connector was pushed onto the port, and then the connected was tuned on clockwise until it clicked. The data collection was set up. On the screen build was pressed following that absolute pressure was pressed, next the 1.23 button was pressed and finally “OK” was pressed. The syringe plunger was set to 60.0mL following that the start button was pressed. Before pushing the plunger the pressure and volume was recorded. As one student pushed the plunger in 5mL at a time the other student recorded the pressure and the corresponding volume. The readings were continued to be written down and the data was set to stop at 35.mL or when the pressure reached 4atm (404kPa). Guy-Lussac’s Law: The home button was pressed following the “do not save”. The pressure sensor and the temperature sensor were connected to the data collection system not to port #2. The Build button was pressed, following the “absolute pressure kPa” button, then the temperature was pressed, next the xy graph button was pressed along with the “OK” button and finally the “periodic” was changed to 1Hz.

was placed tightly into one hole of the rubber stopper and connected to the pressure port of the sensor with a piece of tubing. A drop of glycerin was used in necessary. The temperature sensor was inserted into the other hole in the rubber stopper. A drop of glycerin was added if necessary. Then the 250mL flask was wrapped 15 to 20 times with electric tape. The 800mL beaker that was ¾ full with water was set on a hot plate with a magnetic stirrer on the ring stand. The stirring bar was placed in the beaker. The 250mL Erlenmeyer flask was mounted in the water so that it was covered with water as much as possible. Lastly the stopper was placed tightly into the Erlenmeyer flask.

    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.
