1. Name three properties that are different from those f liquids. Explain the difference of each.
2. What causes surface tension in liquids? Name a substance that has a very high surface tension. What kinds of intermolecular forces account for the high value?
3. Explain how the equilibrium vapor pressure of a liquid might be measured?
4. The surface tension of the liquid decreases with increasing temperature. Using the idea of intermolecular attractions, explain why this is so.
5. Define the heat vaporization of liquid. How is it related to the heat of condensation of that liquid? Using the idea of intermolecular attractions, explain why the process of vaporization is endothermic?
