points (2,24) (3,16) (4,12) (8,6) (12,4)

  1. Using the expression PV = C, Sketch the shape of the graph of your expected results (Pressure is plotted vertically, and Volume is plotted horizontally).
  2. From the Ideal Gas Law (PV = nRT), we know that plotting a PV graph would be an inverse relationship if the number of moles and Temperature remained constant. Add to the graph you just sketched above a new curve that would show what the relationship would look like if the number of moles of the gas increased
  3. How do you know that the constant in PV = C would be nRT?
  4. From the Ideal Gas Law (PV = nRT), we know that plotting a P-T graph would be a direct relationship if the number of moles and Volume remained constant. Sketch a graph of your expected results. (Pressure is plotted vertically, and Temperature is plotted horizontally).
  5. Add to the graph you just sketched above a new curve that would show what the relationship would look like if the number of moles of the gas increased.
  6. How do know that the slope of the line would be nR/V?
