**Transcription for Educational Website** --- **Phase Changes for a Substance: Temperature vs. Kinetic Energy** **Graph Explanation:** The graph displays the relationship between kinetic energy and temperature for a substance undergoing phase changes. The x-axis represents kinetic energy in kilojoules (kJ), ranging from 0 to 1000 kJ. The y-axis indicates temperature in Kelvin (K), ranging from 260 to 340 K. The graph plots several segments labeled A through F, illustrating different stages in the phase change process. - **Segment A to B**: Shows an increase in temperature with an increase in kinetic energy. - **Segment B to C**: The temperature remains constant while kinetic energy continues to increase, indicating a phase change. - **Segment C to D**: Shows another increase in temperature with further kinetic energy increase. - **Segment D to E**: Temperature remains constant again, indicating another phase change. - **Segment E to F**: Temperature increases with kinetic energy. **Questions:** 1. What phase is this substance in at point A? ____________ 2. What phase is this substance in at point F? ____________ 3. What is the general term for what is happening at points B → C and points D → E? ____________ 4. What specifically is happening at points B → C? ____________ 5. What specifically is happening at points D → E? ____________ 6. What specifically is happening at points C → B? ____________ 7. What specifically is happening at points E → D? ____________ 8.

**Phase Changes for a Substance: Temperature vs. Kinetic Energy**
**Graph Explanation:**
The graph displays the relationship between kinetic energy and temperature for a substance undergoing phase changes. The x-axis represents kinetic energy in kilojoules (kJ), ranging from 0 to 1000 kJ. The y-axis indicates temperature in Kelvin (K), ranging from 260 to 340 K. The graph plots several segments labeled A through F, illustrating different stages in the phase change process.
- **Segment A to B**: Shows an increase in temperature with an increase in kinetic energy.
- **Segment B to C**: The temperature remains constant while kinetic energy continues to increase, indicating a phase change.
- **Segment C to D**: Shows another increase in temperature with further kinetic energy increase.
- **Segment D to E**: Temperature remains constant again, indicating another phase change.
- **Segment E to F**: Temperature increases with kinetic energy.
