The following data were collected for a gas sample consisting of 5.00 mol of molecules in a rigid container.

(a) Determine the volume of the sample.

(b) Plot the data either by hand or using a spreadsheet. Now suppose you add another 5.00 mol of gas molecules into the same volume. Plot the corresponding line for the second sample.

(c) At what temperature (in kelvins) do the two lines intersect?

Temperature/C Pressure, P/atm 0 4.48 20 4.80 40 5.14 60 5.46 80 5.80
