It looks like you've uploaded an image of a worksheet titled
"Phases of Matter Math", which is designed to help students understand the changes in states of matter using visual representations and word banks. Since I can't view images directly, I'll interpret the task based on your description and typical content of such worksheets.
Let’s assume the worksheet contains:
1.
Visual diagrams showing phase changes (e.g., solid → liquid → gas).
2.
Blank equations where students must fill in the correct phase change process.
3. A
word bank with terms:
- *heat, gas, melts, solid, liquid, heat, liquid, evaporation*
4. A hint: *"Adding heat gives things (increased) energy."*

Let's solve the problems step by step:
####
Problem 1:
Diagram:
Solid cube + 🔥 → Liquid droplet
Question: When a solid changes to a liquid it ________.
Answer:
This is
melting.
So, the blank should be filled with:
melts
✔ Answer: *When a solid changes to a liquid it
melts.*
> Explanation: Melting is the process where a solid turns into a liquid due to added heat energy breaking the bonds between particles.

Problem 2:
Diagram:
Liquid drop + 🔥 → Gas (steam) + Mug (possibly indicating boiling)
Question: When a liquid changes to a gas it ________.
Answer:
This is
evaporation or
boiling — both are forms of vaporization.
From the word bank: "evaporation" is available.
✔ Answer: *When a liquid changes to a gas it
evaporates.*
> Explanation: Evaporation is the change from liquid to gas, often at the surface. Boiling occurs throughout the liquid at its boiling point. But since “evaporation” is in the word bank, that’s likely the intended answer.

Final Answers:
1. When a solid changes to a liquid it
melts.
2. When a liquid changes to a gas it
evaporates.
---
Key Concept:
- Adding
heat increases the kinetic energy of particles.
- This causes solids to
melt into liquids, and liquids to
evaporate into gases.
---
Word Bank Usage:
Used words:
-
melts (from problem 1)
-
evaporates (from problem 2)
-
heat (mentioned in hint)
Unused words:
- gas, solid, liquid, liquid (repeated), operation — possibly for other parts not shown.

If there are more questions or diagrams (like freezing, condensation, etc.), they might follow similar logic. Let me know if you'd like help with those too!
Parent Tip: Review the logic above to help your child master the concept of change in matter worksheet.
