-DISCUSSION QUESTIONS:
You will often be asked to explain sources of error in your experiments. Imagine there was a
leak in your flask, how would this affect your experimental AHvap for methanol? You need to
first look at how this would affect your measured values and then track those through your
calculations to see how they affect the final value, AHvap. The following series of questions will
guide you through this logic.
1. If there was a slow leak in the flask, would the measured Ptotal be too high, too low or not
affected? Briefly justify your answer.
