1. What sources of error could there have been in the part of the experiment where you boiled the substances? 2. What could you have done to reduce those errors?

3. The vapor pressure of a liquid is a measure of how much vapor of a liquid sits in the air above the liquid in a closed container. So, for example, a steam room has a very high vapor pressure of water. Do you think a substance that has weaker forces between molecules would in general have a greater or lesser vapor pressure than a substance with stronger forces between the molecules? For example, compare isopropyl alcohol and water.
