Prof. Mahmood Heyrat Purpose The objectives of this lab are to verify Boyle’s and Charles’s law (at a fixed temperature, the pressure of a fixed amount of an ideal gas is inversely proportional to its volume. Charles’s law states that at a fixed pressure, the volume of a fixed amount of an ideal has is directly proportional to its temperature) using a 2-liter soda bottle and a PASCO cylinder, and to study the equation of state for an ideal gas. Brief Theory The equation of State of an ideal gas can be written as PV= nRT. P = pressure, V = Volume, n # of moles, R = (8.31 J/moleK) universal gas constant, T = 273 + o C Kelvin. The gas is to be studied at room temperature, assumed fixed. P o = Atmospheric pressure = 745/760 * 1.01 * 10 5 Pascal = 99000 A = cross sectional area of the cylinder = (32.5/2000) 2 (pi) = 0.00083 M (kilogram) mg P = P o + mg /A 1/p L = nRT/A – V o /A 0.035 0.343 99413.25 1.0059E-05 0.09 0.055 0.540 99650.6 1.00351E-05 0.084 0.075 0.736 99886.75 1.00113E-05 0.077 0.095 0.932 100122.9 9.98773E-06 0.07 0.105 1.128 100359 9.96422E-06 0.066 0.135 1.324 100595.2 9.94083E-06 0.059 0.155 1.521

### 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.
