It looks like you've uploaded a worksheet titled
"States of Matter and Phase Changes (Work/Sheet)", which includes several questions about the states of matter and phase changes. Since I can't view images directly, I'll interpret the content based on your description and typical structure of such worksheets.
Let’s go through each question and provide the correct answers along with explanations:
---
Q1: Use the words in the box to label the states of matter.
You have three images:
-
Image 1: Red cubes stacked in a fixed pattern → This represents
solid.
-
Image 2: Red spheres in a container, filling it but not taking shape → This represents
liquid.
-
Image 3: Red spheres scattered randomly, spreading out → This represents
gas.
✔ Answers:
- Image 1:
Solid
- Image 2:
Liquid
- Image 3:
Gas
>
✔ Explanation:
> -
Solids have a definite shape and volume. Particles are tightly packed and vibrate in place.
> -
Liquids have a definite volume but no definite shape (they take the shape of the container). Particles are close but can move past one another.
> -
Gases have neither definite shape nor volume. Particles are far apart and move freely.

Q2: Which state of matter does NOT have a definite volume or shape?
A) Solid
B) Liquid
C) Gas
✔ Answer: C) Gas
>
✔ Explanation: Gases expand to fill their container, so they have
no definite shape or volume.
---
Q3: Which state of matter has a definite volume but no definite shape?
A) Solid
B) Liquid
C) Gas
✔ Answer: B) Liquid
>
✔ Explanation: Liquids maintain a fixed volume but flow and take the shape of their container.
---
Q4: Which state of matter has a definite shape and volume?
A) Solid
B) Liquid
C) Gas
✔ Answer: A) Solid
>
✔ Explanation: Solids keep their shape and volume due to strong intermolecular forces.

Q5: Use the arrows in the box to label each arrow with the correct phase change.
There is a diagram showing a cycle between
SOLID,
LIQUID, and
GAS with arrows connecting them.
The phase changes are:
-
Solid → Liquid:
Melting
-
Liquid → Solid:
Freezing
-
Liquid → Gas:
Evaporation (or Vaporization)
-
Gas → Liquid:
Condensation
-
Solid → Gas:
Sublimation
-
Gas → Solid:
Deposition
Now, match the arrows accordingly.
✔ Labeling:
-
Solid → Liquid:
Melting
-
Liquid → Solid:
Freezing
-
Liquid → Gas:
Vaporization
-
Gas → Liquid:
Condensation
-
Solid → Gas:
Sublimation
-
Gas → Solid:
Deposition
>
✔ Explanation:
> These are the six phase changes:
> -
Melting – solid to liquid
> -
Freezing – liquid to solid
> -
Vaporization – liquid to gas (includes evaporation and boiling)
> -
Condensation – gas to liquid
> -
Sublimation – solid to gas (e.g., dry ice)
> -
Deposition – gas to solid (e.g., frost forming)

Final Answers Summary:
| Question | Answer |
|--------|--------|
| Q1 | Solid, Liquid, Gas (in order of images) |
| Q2 | C) Gas |
| Q3 | B) Liquid |
| Q4 | A) Solid |
| Q5 | Arrows labeled as: Melting, Freezing, Vaporization, Condensation, Sublimation, Deposition |

If you can describe any part of the image more clearly (e.g., if there's a specific diagram or confusion), I’d be happy to clarify further!
Parent Tip: Review the logic above to help your child master the concept of phase changes worksheet.
