Phase Diagram Exploration

Phase Diagram Exploration

Read each question carefully and answer to the best of your ability. Use the provided phase diagram to answer the questions.

Study the provided generic phase diagram below to answer the following questions.

1. What is the state of matter at high pressure and low temperature?

2. What phase change occurs when moving from the solid region to the liquid region?

3. Identify the special point on the phase diagram where all three phases coexist in equilibrium.

4. Above the critical point, a substance exists as a:

5. Sublimation is the phase change from liquid to gas.

6. The boundary line between the solid and liquid phases is called the   curve.

7. When a substance goes directly from a gas to a solid, it is called  .

8. Explain how a phase diagram can be used to determine the boiling point of a substance at a specific pressure.
