Phases of Matter - Gas, Liquids, Solids - Free Printable

The image is a "Phases of Matter - Vocabulary Quiz" that asks you to name the six ways the phase (state) of matter changes, based on the diagram showing transitions between solid, liquid, and gas.

Let’s analyze the diagram:

- Top: Ice cubes (solid)
- Bottom left: Glass of water (liquid)
- Bottom right: Kettle with steam (gas)

There are six arrows labeled 1 through 6, showing transitions between these states. The task is to identify each phase change.

Step-by-step explanation:

#### Arrow 1: Solid → Liquid
- Ice melts into water.
- This is melting.

#### Arrow 2: Liquid → Solid
- Water freezes into ice.
- This is freezing.

#### Arrow 3: Gas → Solid
- Steam (gas) turns directly into ice (solid).
- This is deposition.

#### Arrow 4: Solid → Gas
- Ice sublimates directly into vapor (e.g., dry ice).
- This is sublimation.

#### Arrow 5: Liquid → Gas
- Water boils and turns into steam.
- This is evaporation or boiling (both are forms of vaporization).

#### Arrow 6: Gas → Liquid
- Steam condenses into water droplets.
- This is condensation.

Final Answer:

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

> ✔ These are the six phase changes of matter:
>
> - Melting (solid → liquid)
> - Freezing (liquid → solid)
> - Evaporation/Boiling (liquid → gas)
> - Condensation (gas → liquid)
> - Sublimation (solid → gas)
> - Deposition (gas → solid)

Summary:

The six ways the phase of matter changes are:

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

These are the fundamental physical changes in state that occur due to temperature and pressure changes.
