V = πr 2 h V = π(.125cm) 2( 5.9cm) = 0.29cm 3 Boyle’s Law P air = P sensor + P atm P air = 27.1mmHg +717mmHg = 744.1mmHg PV = k 744.1mmHg x 19ml = 14137.9 Results and Conclusions Part A Temperature ( o C) Temperature ( o K) Height of air (cm) Volume (cm 3 ) 6 279 5.9 0.29 23 296 6.0 0.29 34 307 6.0 0.29 49 322 6.2 0.30 63 336 6.5 0.32 77 350 6.7 0.33 93 366 7.0 0.34 Conclusion: As the temperature increases the volume increases as well. V vs. T is a direct relationship. As the temperature increases so does the volume. Volume (ml) = .0197(Temp (K)) + 0.098

### What students are saying

• 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.
