Problem Analysis:
The image provided is a
Phase Change Diagram that illustrates the transitions between different states of matter (solid, liquid, gas) as heat energy is added or removed. The task is to fill in the rectangles with appropriate vocabulary related to phase changes and particle behavior.
Key Concepts:
1.
States of Matter: Solid, Liquid, Gas.
2.
Phase Changes:
-
Melting: Solid → Liquid.
-
Freezing: Liquid → Solid.
-
Vaporization (Boiling): Liquid → Gas.
-
Condensation: Gas → Liquid.
-
Sublimation: Solid → Gas.
-
Deposition: Gas → Solid.
3.
Particle Behavior:
- In a
solid, particles are closely packed and vibrate in place.
- In a
liquid, particles are close but can move past each other.
- In a
gas, particles are far apart and move freely.
Solution:
We will analyze the diagram step by step and fill in the rectangles accordingly.
#### 1.
Rectangle A (Solid State):
- The particles are closely packed and vibrate in place.
-
Label:
Solid
#### 2.
Rectangle B (Melting Process):
- This is the process where a solid turns into a liquid as heat is added.
-
Label:
Melting
#### 3.
Rectangle C (Liquid State):
- The particles are close together but can move past each other.
-
Label:
Liquid
#### 4.
Rectangle D (Boiling Process):
- This is the process where a liquid turns into a gas as heat is added.
-
Label:
Boiling
#### 5.
Rectangle E (Gas State):
- The particles are far apart and move freely.
-
Label:
Gas
Final Filled Diagram:
-
A: Solid
-
B: Melting
-
C: Liquid
-
D: Boiling
-
E: Gas
Explanation:
-
A (Solid): Particles are tightly packed and vibrate in place.
-
B (Melting): Heat is added, and the particles gain enough energy to overcome intermolecular forces, transitioning from a solid to a liquid.
-
C (Liquid): Particles are closer than in a gas but can move past each other.
-
D (Boiling): More heat is added, and the particles gain enough energy to escape the liquid state and become a gas.
-
E (Gas): Particles are far apart and move freely in all directions.
Final Answer:
\[
\boxed{\text{A: Solid, B: Melting, C: Liquid, D: Boiling, E: Gas}}
\]
