CHAPTER 12
Chapter 12 Review
14. List three assumptions of the kinetic-molecular theory.
15. Which has a lower density—oxygen gas or silver? Explain your
answer.
16. Distinguish between diffusion and effusion.
17. Which of these gases will diffuse the fastest: CO, Xe , or He?
The slowest? Explain your answers.
18. Do all of the particles in a sample of nitrogen gas have the
same kinetic energy at 100 K? Explain your answer.
19. Use what you learned in this chapter about viscosity to explain
which container of maple syrup will take the longest to pour
over pancakes: a container that has been refrigerated, one that
has been microwaved, or one kept at room temperature?
20. List three properties of liquids.
21. Explain why some liquids form a convex surface when placed
in a narrow test tube, while others form a concave surface.
22. Why do gases diffuse more quickly than do liquids?
23. What general property of solids accounts for their high density?
24. How does an amorphous solid differ from a crystalline solid?
25. Identify each process.
a. solid 0 liquid
b. solid 0 gas
c. liquid 0 solid
d. liquid 0 gas
e. gas 0 liquid
f. gas 0 solid
