Chapter 11, Problem 11.80(choose chapter or problem)
Ethylene glycol (HOCH2CH2OH) and pentane (C5H12) are both liquids at room temperature and room pressure, and have about the same molecular weight.
(a) One of these liquids is much more viscous than the other. Which one do you predict is more viscous?
(b) One of these liquids has a much lower normal boiling point (36.1 °C) compared to the other one (198 °C). Which liquid has the lower normal boiling point?
(c) One of these liquids is the major component in antifreeze in automobile engines. Which liquid would you expect to be used as antifreeze?
(d) One of these liquids is used as a “blowing agent” in the manufacture of polystyrene foam because it is so volatile. Which liquid would you expect to be used as a blowing agent?
