To solve the problem and explain the solution, let's analyze the phase changes of matter as depicted in the diagram. The goal is to match the correct phase changes with their corresponding energy interactions (adding or removing heat energy) and place them in the appropriate boxes.
Key Concepts:
1.
Phase Changes:
-
Melting: Solid → Liquid (requires adding heat energy)
-
Freezing: Liquid → Solid (requires removing heat energy)
-
Evaporation: Liquid → Gas (requires adding heat energy)
-
Condensation: Gas → Liquid (requires removing heat energy)
2.
Energy Interaction:
-
Add Heat Energy: Melting, Evaporation
-
Remove Heat Energy: Freezing, Condensation
Step-by-Step Solution:
#### 1. Identify the Phases:
-
Left Beaker: Contains a solid (ice cube).
-
Middle Beaker: Contains a liquid (water).
-
Right Beaker: Contains a gas (steam).
#### 2. Match Phase Changes with Energy Interactions:
-
From Solid to Liquid (Melting): Requires adding heat energy.
-
From Liquid to Solid (Freezing): Requires removing heat energy.
-
From Liquid to Gas (Evaporation): Requires adding heat energy.
-
From Gas to Liquid (Condensation): Requires removing heat energy.
#### 3. Place the Labels in the Diagram:
-
Top Row (Arrows Pointing Right):
-
Solid → Liquid: Melting (Add heat energy)
-
Liquid → Gas: Evaporation (Add heat energy)
-
Bottom Row (Arrows Pointing Left):
-
Gas → Liquid: Condensation (Remove heat energy)
-
Liquid → Solid: Freezing (Remove heat energy)
#### 4. Final Placement:
-
Top Row (Arrows Pointing Right):
- First box: Melting (Add heat energy)
- Second box: Evaporation (Add heat energy)
-
Bottom Row (Arrows Pointing Left):
- First box: Freezing (Remove heat energy)
- Second box: Condensation (Remove heat energy)
Final Answer:
\[
\boxed{
\begin{array}{ccc}
\text{Melting} & \text{Evaporation} \\
\text{(Add heat energy)} & \text{(Add heat energy)} \\
\hline
\text{Freezing} & \text{Condensation} \\
\text{(Remove heat energy)} & \text{(Remove heat energy)}
\end{array}
}
\]
This completes the task by correctly matching the phase changes with their respective energy interactions and placing them in the diagram.
