Abstract The purpose of this experiment was to explore and verify ideal gas laws. The ideal gas law is a physical law describing the relationship of the measurable properties of an ideal gas , where P (pressure) × V (volume) = n (number of moles) × R (the gas constant) × T (temperature in Kelvin). This laboratory specifically examined Boyle’s Law and Gay-Lussac’s Law. Boyle’s Law is a law stating that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature and it denoted mathematically as: V α 1/P. Gay-Lussac’s Law states that, for a given mass and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature and is denoted mathematically as: P α T. In order to verify Boyle’s Law, the temperature of gas inside a syringe was kept constant while the volume was slowly decreased manually. The syringe was connected to a pressure sensor via a tube. The Logger Pro Program “Boyle’s Law” collected the change in pressure of the gas. This data was then used to determine the number of moles of air to be 9.87*10-4 moles and number of air molecules contained in the syringe to be 5.94*1020 molecules. In order to verify Gay-Lussac’s Law, a 2-way valve was connected to the syringe and the pressure sensor. The syringe was placed into a stainless steel beaker and gradually heated via a hot plate. A temperature sensor was used to monitor the temperature change of the apparatus.

### 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.
