Explanation:

To identify the state changes, we recall the phase transitions between solid, liquid, and gas:

1. Solid to Gas: Sublimation (when a solid turns directly to gas, e.g., dry ice to $CO_2$ gas).
2. Gas to Solid: Deposition (when a gas turns directly to solid, e.g., frost formation).
3. Solid to Liquid: Melting (when a solid is heated to become liquid, e.g., ice to water).
4. Liquid to Solid: Freezing (when a liquid is cooled to become solid, e.g., water to ice).
5. Liquid to Gas: Evaporation (or Boiling, when a liquid turns to gas, e.g., water to steam).
6. Gas to Liquid: Condensation (when a gas cools to become liquid, e.g., steam to water).

Matching these to the diagram's arrows:

• Arrow 1 (Solid → Gas): Sublimation
• Arrow 2 (Gas → Solid): Deposition
• Arrow 3 (Solid → Liquid): Melting
• Arrow 4 (Liquid → Solid): Freezing
• Arrow 5 (Liquid → Gas): Evaporation (or Boiling)
• Arrow 6 (Gas → Liquid): Condensation

Answer:

1. Sublimation
2. Deposition
3. Melting
4. Freezing
5. Evaporation (or Boiling)
6. Condensation
