7. Which one of the following has the highest IMF and why (explain in space below), H2O , CH3CH2OH, or NH3.
8. Define evaporation including where and when does it occur?
9. Explain why the more detailed definition of Boiling point is the temperature where the vapor pressure of the liquid = atmospheric pressure.
10. Crude oil is a mixtures of compounds. Two of these compounds are hexane (C6H14) and octane (C8H18). What is the physical process called that separates these two liquid? What property is this physical process based on? Both of these substance have _________________ IMF. Which one has the higher IMF and why? Which one boils first?
11. Using your knowledge of IMF, explain why vegetable oil and water do not mix or do not dissolve in each other. Is that the correct words to use with these two substance? If not, what are/is the correct word(s)?
12. Substance A has a greater IMF than Substance B, would it "make sense" (from knowledge of IMF) that Substance A is a gas whereas Substance B is a liquid (both substance are at the same temperature? Explain.
