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:
Liquid
Gas
Supercritical fluid
Plasma
5. Sublimation is the phase change from liquid to gas.
True
False
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.
