The labels in the diagram represent changes of state and descriptions in a phase diagram. Freezing (solid to liquid) involves the strengthening of attractive forces. Melting (liquid to solid) results from weakening forces with added heat. Evaporation/boiling (liquid to gas) and condensation (gas to liquid) relate to altering heat and particle kinetic energy.
Matching the labels with the correct change of state or description:
1. \(a\) - **Freezing (A: Solid to Liquid):**
- The removal of heat energy slows down the particles, and the attractive forces between them get stronger.
2. \(b\) - **Melting (B: Liquid to Solid):**
- The addition of heat energy weakens the attractive forces between particles. The kinetic energy of the particles overcomes the forces of attraction.
3. \(c\) - **The addition of heat energy weakens the attractive forces between particles. The kinetic energy of the particles overcomes the forces of attraction.**
- This description matches with the process of \(d\) - **Evaporation or Boiling (D: Liquid to Gas).**
4. \(d\) - **Evaporation or Boiling (D: Liquid to Gas):**
- The addition of heat energy weakens the attractive forces between particles. The kinetic energy of the particles overcomes the forces of attraction.
5. \(e\) - **Condensation (C: Gas to Liquid):**
- The removal of heat energy slows down the particles, and the attractive forces between the particles get stronger.
Therefore, the correct matches are:
- \(a\) - Freezing
- \(b\) - Melting
- \(c\) - Evaporation or Boiling
- \(d\) - Liquid to Solid
- \(e\) - Condensation
