Phase Change in Matter Worksheet Interactive Worksheet - Edform - Free Printable

Part One: Fill in the Blanks

The task involves filling in the blanks using the word bank provided. The diagram shows three states of matter (solid, liquid, gas) and the processes that cause transitions between these states. Let's analyze the diagram step by step:

#### Diagram Analysis:
1. Left Column (Solid):
- The solid state is represented by ice.
- Adding heat energy to a solid causes it to melt into a liquid.
- Removing heat energy from a liquid causes it to freeze into a solid.

2. Middle Column (Liquid):
- The liquid state is represented by water.
- Adding heat energy to a liquid causes it to evaporate into a gas.
- Removing heat energy from a gas causes it to condense into a liquid.

3. Right Column (Gas):
- The gas state is represented by vapor.
- Adding heat energy to a gas does not change its state but increases its temperature.
- Removing heat energy from a gas causes it to condense into a liquid.

#### Filling in the Blanks:
Using the word bank, we can fill in the blanks as follows:

- Top Left (Solid → Liquid): Melting
- Bottom Left (Liquid → Solid): Freezing
- Top Middle (Liquid → Gas): Evaporation
- Bottom Middle (Gas → Liquid): Condensation
- Top Right (Liquid → Gas): Add heat energy
- Bottom Right (Gas → Liquid): Remove heat energy

#### Final Filled Diagram:
```
Solid Liquid Gas
↓ ↓ ↓
Melting Evaporation Add heat energy
↑ ↑ ↑
Freezing Condensation Remove heat energy
```

Part Two: Phase Change Read, Discuss, Respond

#### Passage Analysis:
The passage describes a scenario where Ms. Staal makes a glass of lemonade with ice and places it outside on a hot day. After a few minutes, she notices that her hand is wet when she picks up the glass. This indicates that water has formed on the outside of the glass.

#### Identifying the Phase Change:
1. Name of Phase Change: Condensation
- Condensation occurs when water vapor in the air changes from a gas to a liquid due to cooling.

2. State of Matter 1: Gas (water vapor in the air)
3. State of Matter 2: Liquid (water droplets on the glass)

#### Description of What Occurred:
- The glass of lemonade is cold because of the ice inside. When the cold glass comes into contact with the warm, humid air outside, the water vapor in the air loses heat energy as it touches the cold surface of the glass.
- As the water vapor loses heat energy, it undergoes condensation, changing from a gas to a liquid. This results in water droplets forming on the outside of the glass.

#### Drawing of Particles:
- Before (Gas): Represent water vapor molecules as widely spaced particles moving rapidly.
- After (Liquid): Represent water molecules as more closely packed particles moving less rapidly.

Final Answer:

Part One:
```
Solid Liquid Gas
↓ ↓ ↓
Melting Evaporation Add heat energy
↑ ↑ ↑
Freezing Condensation Remove heat energy
```

Part Two:
1. Name of Phase Change: Condensation
2. State of Matter 1: Gas
3. State of Matter 2: Liquid
4. Description of what occurred: Water vapor in the air lost heat energy when it came into contact with the cold glass, causing it to condense into liquid water droplets on the outside of the glass.
