Sharon Yoon January 15, 2012 Ms. Bland-Lamoureux LAB #13: GAS LAWS: Group 5 ABSTRACT: 1. Gas laws are based on relationships between temperature, pressure, and volume of a sample of gas. 2. A vacuum pump was used to understand the gas laws. 3. A balloon was placed into the jar and expanded as air was pumped out of the vacuum due to a decrease in the atmospheric pressure. 4. The actions of the balloon observed Boyle’s law because at a constant temperature, there was an inversely proportional relationship between the volume and pressure of the air. QUESTIONS: I. 1. What is inside the bell jar now? Trapped gas is inside the bell jar. 2. Where does the air come from that fills the syringe? The air comes from E through the hose with tee. 3. Where did the air go that was in the syringe? The air went out through E. 4. Describe, in words, the amount of force that was required to pull out the piston.

    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.
