Ch. 9&10 Please help with question 4 (d-f) **Educational Website Content: Phase Diagram Analysis**---### Phase Changes and Diagrams#### Questions1. **Label Phase Changes** - **B**: Boiling begins. - **E**: Freezing begins. - **F**: Condensation begins.2. **Energy and Temperature Analysis** - **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?** - Answer: 10 grams melt into 10 grams of water at point C.3. **Phase Diagram Exploration** **4. Using the phase diagram to the right:** - **a. Label each phase in the diagram in the box provided.** - Phases: Solid, Liquid, Gas - **b. What is the normal melting and normal boiling point?** - Normal melting point: 54.8 Kelvin - Normal boiling point: 290.2 Kelvin - **c. What is the phase change associated with letter A when the pressure is suddenly dropped?** - Answer: Gas phase - **d. What singular change can you do to letter B to vaporize it?** - [Response is expected from the user.] - **e. What is happening on the molecular level for your answer in part D to work?** - [Response is expected from the user.] - **f. What is the vapor pressure of this substance at approximately 80K?** - [Response is expected from the user.]#### Diagrams- **Phase Diagram**: A graph of Temperature vs. Energy is provided. The diagram indicates different states of matter (solid, liquid, gas) at various points: - Energy increases from left to right. - Temperature increases from bottom to top. - Key phases include transitions such as solid to liquid, and liquid to gas.- **Small Diagram**: The diagram on the right displays phases labeled as solid, liquid, and gas across different pressures and temperatures. Key points are plotted such as the normal melting and boiling points marked in Kelvin.---This content is designed for educational purposes, helping students understand phase changes and the interpretation of phase diagrams.
