How would temperature affect the vapour pressure of a non polar solvent

Question

 Give example and description 

Answer 1

At higher temperature, the vapor pressure will increase.  Vapor pressure is the equilibrium pressure pressure of the vapor above the liquid.  Depending on the intermolecular forces holding the liquid molecules together, it may take a higher or lower temperature to increase the vapor pressure.  For example, the temperature need to increase the vapor pressure of propane would be less than that to increase the vapor pressure of hexane, mainly because while both are non polar, hexane will have stronger intermolecular forces, and so would require more energy (higher temperature) to increase vapor pressure.
