Assuming that the leak was a constant amount (meaning the same proportion leaked at all data points), how would the calculated AHvap be affected? Hint: If you are having trouble tracking the effect from Pyap to AHvap. you can try creating a hypothetical graph using your excel data file (use a different file than the one you will submit). Create a new column where you change Pyap according to your answers to previous questions", then calculate a new Ln Pvap- You should graph both the real Ln Pvap and this hypothetical one on the same chart to see how the data compares. Ask yourself what changed and how that would affect AHvap. "For this to work you will need to use a proportion not a value. Example: let's say you decided that Pvap is being lowered so you need to decrease Pyap. You need to lower every Pvap by a proportion (say 10% lower) not an actual number. To do this in excel you can insert a "changed Pyap" column and use a formula such as Pvap cell"0.9 (that would be a 10 % decrease)…
