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.
