Question Set: Phase Changes and Pressure
Table of Contents
- Compare the densities of a solid, liquid, and gas. Is one phase usually denser than the others? Is one phase usually less dense? Explain your answer using examples.
- Give examples for as many of the phase changes as you can shown in Fig. 5-4 and listed below:
- Vaporization
- Condensation
- Sublimation
- Deposition
- Freezing
- Melting
- Which changes in Fig. 5-4 require energy? Which give off energy?
- In Fig. 5-7, the triple point (T. Pt) of water is labeled. What do you think the triple point means? (Hint: look at the lines delineating the phases of water.) What is unique about the triple point? Does it ever occur in nature?
