I. Pressure, Volume Relationship The relationship between pressure and volume of a gas is given by Boyle's Law (PV = k). A sample gas trapped in a large calibrated syringe can have pressure applied to it.

Include all of the pertinent data and components that must accompany this graph as described in the Background Video. (b) Using Excel, prepare a graph of 1/V vs. P using the same data. Include all of the pertinent data and components that must accompany this graph as described in the Background Video. (c) State which graph is more linear and explain how you know this.
