**Phase Changes and Diagram Analysis** 1. **Labeling Phase Changes:** - A: Melting begins - B: Boiling begins - C: Freezing begins - D: Condensation begins 2. **Temperature-Energy Diagram Explanation:** - The diagram displays phases as temperature (vertical axis) increases with energy (horizontal axis). - Region from A to B: Solid phase transitions to solid-liquid mixture (melting). - Region from D to E: Liquid phase transitions to liquid-gas mixture (boiling). 3. **Suppose you have 10 grams of water at 25°C. What do you need to do to get the 10 grams of water to point C?** - 10 grams melt into 10 grams of water at point C. 4. **Using the Phase Diagram on the Right:** a. **Labeling Phases in the Diagram:** - Point 54.4 Kelvin: Solid - Point 154.6 Kelvin: Gas - Region between points A and B: Solid - Region between points B and Q: Liquid b. **Normal Melting and Boiling Points:** - Normal melting point = 54.8 Kelvin - Normal boiling point = 90.2 Kelvin c. **Phase Change at Letter A with Sudden Pressure Drop:** - Gas phase d. **Singular Change to Letter B to Vaporize It:** - Increase temperature e. **Molecular Level Explanation for Part D:** - Increase in kinetic energy causes molecules to overcome intermolecular forces, leading to vaporization. f. **Vapor Pressure at Approximately 80K:** - Determined from diagram or data table (details not provided in the text).
