Carefully read each question and refer to the phase diagram provided to determine your answers. Show all calculations where applicable.
Refer to the generic phase diagram below to answer the following questions.
1. What phases of matter are present at the Triple Point?
2. Describe the state of matter beyond the Critical Point.
3. Which of the following phase changes occurs when a substance goes directly from a solid to a gas?
Melting
Evaporation
Sublimation
Condensation
4. Increasing the pressure on a substance generally favors which phase?
Solid
Liquid
Gas
Plasma
5. The line separating the solid and liquid phases is called the curve.
6. At pressures and temperatures above the critical point, a substance exists as a fluid.
7. For most substances, the solid-liquid coexistence line slopes to the right (positive slope).
True
False
8. Boiling is a phase transition that occurs when a liquid changes to a gas at a specific temperature and pressure.
True
False
9. Explain the difference between boiling and evaporation in terms of temperature and pressure conditions.
10. How does the phase diagram for water differ from most other substances, particularly concerning the solid-liquid boundary?
