In part three you will determine the number of moles of gas in your apparatus from a plot of volume versus pressure.

In the second part, you will measure the pressure and temperature for two different volumes and verify the ideal gas law.

We might ask, though, how did we get the Ideal Gas Law? It should be close to 20 cc.

We now examine the actual process of mixing two gases together and measuring the total pressure.

Figure This result is known as Charles' Law, dating to Figure 6 shows the opening screen in DataStudio. Determine the mole fractions and partial pressures of the components of dry air at standard pressure. The Ideal Gas Law reveals that the pressure exerted by a mole of molecules does not depend on what those molecules are, and our earlier observation about gas mixtures is consistent with that conclusion. Figure 8: Plunger set at 40 cc 8 Now re-connect the coupler to the sensor. We would like to derive the Ideal Gas Law from the three experimental observations. Figure 9: Screenshot showing the two graphs 14 The initial pressure of the gas is the pressure before you compressed the air when the volume was at 40 cc and the gas was at room temperature. Sketch a graph with two curves showing Volume vs. Explain the comparison of the two curves. Figure 9 shows the general shapes of the two graphs. Sketch a graph with two curves showing Pressure vs.

Figure 9: Screenshot showing the two graphs 14 The initial pressure of the gas is the pressure before you compressed the air when the volume was at 40 cc and the gas was at room temperature.

Description of apparatus The apparatus is comprised of a plastic syringe with a plunger, a pressure sensor and a temperature sensor. We would like to derive the Ideal Gas Law from the three experimental observations.

The plunger handle should be all the way down and flush against the mechanical stop. Observation 3: Partial Pressures We referred briefly above to the pressure of mixtures of gases, noting in our measurements leading to Boyle's Law that the total pressure of the mixture depends only on the number of moles of gas, regardless of the types and amounts of gases in the mixture.

This result is known as Charles' Law, dating to Record these values in Data Table 1. Amonton's Law says that the pressure of a gas is proportional to the absolute temperature for a fixed quantity of gas in a fixed volume.

The results of three observations relate these four properties pairwise.
