**Phase Diagram Exercise**

4. **Using the phase diagram to the right:**

a. **Label each phase in the diagram to the right in the box provided.**

The diagram shows regions labeled as A, B, and a point marked Q. These regions typically represent different phases of a substance: solid, liquid, and gas.

b. **What is the normal melting and normal boiling points?**

Determine the temperature and pressure at which the substance transitions from solid to liquid (melting) and liquid to gas (boiling) at 1 atm.

c. **What is the phase change associated with letter A when the pressure is suddenly dropped?**

Analyze how the phase at letter A will change if there is a sudden decrease in pressure, such as solid to gas or liquid to vapor.

d. **What singular change can you do to letter B to vaporize it?**

Identify a single change in either temperature or pressure that will cause the substance at letter B to enter the vapor phase.

e. **What is happening on the molecular level for your answer in part D to work?**

Explain the molecular dynamics, such as increased molecular movement or breaking of intermolecular forces, that facilitate the phase change.

f. **What is the vapor pressure of this substance at approximately 80K?**

Read the graph to find the vapor pressure corresponding to the temperature of 80 Kelvin.

**Phase Diagram Description:**

- **Axes:** The x-axis represents temperature in Kelvin, and the y-axis represents pressure in atmospheres.
- **Curves and Points:**
- The diagram includes a curve that indicates the boundaries between different phases.
- Regions marked as A, B, and a point Q, likely indicate solid, liquid, and gas phases or transition points.

**Note:** The specific details, such as the type of substance and accurate phase labeling, depend on interpretation from the given diagram data.
