States of matter worksheets - Free Printable

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. A series of diagrams showing phase changes (e.g., solid → liquid → gas).
2. Word bank with terms: *heat, gas, solid, liquid, cold, heat, liquid, condensation*.
3. Instructions to "Complete each sentence with the words in the word bank."

Here’s how we can solve this step-by-step, assuming the following:

---

Problem 1:

Diagram:
Solid (ice cube) → [arrow] → Liquid (water droplet)

Sentence:
"When a solid changes to a liquid it ___."

✔ Answer: *"melts"* — but since "melt" isn't in the word bank, we look for related terms.

Wait — the word bank includes:
heat, gas, solid, liquid, cold, heat, liquid, condensation

Note: "heat" appears twice, likely a typo or emphasis.

So possible correct answer must be built from those words.

Let’s reevaluate.

Reassessing Based on Common Phrases:

#### Sentence 1:
"When a solid changes to a liquid it ___."

Common phrase: "it melts" — but "melt" not in word bank.

But we know that adding heat causes melting.

So perhaps the sentence is structured as:

> "When a solid changes to a liquid it needs heat."
Or
> "When a solid changes to a liquid it is heated."

But if the blank is only one word, then maybe the intended answer is "melts" — but again, not in word bank.

Alternatively, the worksheet may have a fill-in-the-blank structure like:

> "When a solid changes to a liquid it ___."
> Options: heat / cold / gas / liquid / solid / condensation

But “melting” isn’t listed. So likely, the answer is:

👉 "absorbs heat" — but again, not in word bank.

Wait — perhaps the sentence is incomplete, and we are to choose from the word bank.

Let’s suppose the sentence is:

> "When a solid changes to a liquid it ___ energy."

And the word bank includes: heat — which means thermal energy.

So:

✔ Answer: *adds heat* or *requires heat*

But the word bank says: "Adding heat gives things (increased) energy." — so likely, "heat" is the key term.

So let's reconstruct:

---

Likely Structure of the Worksheet:

#### Question 1:
Diagram: Ice → Water
Sentence: When a solid changes to a liquid it ___.

Word Bank: heat, gas, solid, liquid, cold, heat, liquid, condensation

→ Best fit: "absorbs heat" — but not fully in word bank.

Wait — perhaps the sentence is:

> "When a solid changes to a liquid it ___."

And the answer is simply: "melts" — but not in word bank.

This suggests the worksheet might use phrases rather than single words.

Alternatively, the sentence might be:

> "When a solid changes to a liquid it ___."

And the word bank allows us to pick "heat", meaning the process requires heat.

So perhaps the full sentence is:

> "When a solid changes to a liquid it requires heat."

But again, "requires" isn't in the bank.

Wait — look at the last line:

> "Adding heat gives things (increased) energy."

That’s a clue!

So the process of changing from solid to liquid involves adding heat.

Thus, the answer to question 1 is likely:

> "When a solid changes to a liquid it gains heat" or "needs heat".

But given the word bank, and the fact that "heat" is repeated, probably the expected answer is:

👉 "heat"

So the completed sentence would be:

> "When a solid changes to a liquid it heat." — but that doesn't make sense grammatically.

Ah! Perhaps the sentence is:

> "When a solid changes to a liquid it is heated."

But again, not matching.

Wait — maybe the sentence is:

> "When a solid changes to a liquid it ___."

And the answer is "melts", but not in the word bank.

Alternatively, the diagram shows ice → water → steam.

Let’s try to reconstruct the actual questions.

Most Likely Interpretation:

The worksheet has two problems:

---

#### Problem 1:
Diagram: Solid (ice) → Liquid (water)
Sentence: When a solid changes to a liquid it ___.

From science knowledge: This is melting, which requires heat.

Since "heat" is in the word bank, and the hint says "Adding heat gives things (increased) energy," the answer is likely:

👉 "needs heat" or just "heat" — but grammar matters.

Perhaps the sentence is:

> "When a solid changes to a liquid it ___."

And the student is to choose "heat" as the missing word — but that’s incorrect.

Alternatively, the sentence may be:

> "A solid changes to a liquid when it ___."

Then the answer could be "heats up" — still not in word bank.

Another idea: Maybe the word bank is meant to be used to complete phrases like:

- "solid → liquid = melting"
- "liquid → gas = evaporation"

But the worksheet says "complete each sentence with the words in the word bank."

Let’s assume the sentences are:

1. When a solid changes to a liquid it ___.
2. When a liquid changes to a gas it ___.

And the word bank is: heat, gas, solid, liquid, cold, heat, liquid, condensation

Now, consider:

- Solid → liquid: melting — requires heat
- Liquid → gas: evaporation — also requires heat
- Gas → liquid: condensation — releases heat
- Liquid → solid: freezing — loses heat

So:

#### Question 1:
"When a solid changes to a liquid it ___."

Answer: "absorbs heat" — but not in word bank.

But "heat" is in the word bank. Maybe the sentence is:

> "When a solid changes to a liquid it ___ energy."

Then the answer is "gains" — but not in word bank.

Wait — the last sentence says:

> "Adding heat gives things (increased) energy."

So the concept is: Heat = energy added

So perhaps the answer is simply:

> "When a solid changes to a liquid it needs heat."

But if only one word is allowed, and the word bank has "heat", then:

👉 Answer: heat

But that's awkward.

Alternatively, the sentence might be:

> "When a solid changes to a liquid it becomes a ___."

Then answer: liquid

But that seems too simple.

Wait — let’s look at the second question.

---

#### Problem 2:
Diagram: Liquid (water droplet) → Gas (steam) → Mug (maybe hot tea?)

Wait — the diagram shows:
Water droplet → Flame → Mug?

Possibly: Liquid → Gas → Then something else?

But more likely:

Liquid → Gas (evaporation), and the mug is just a container.

So:

> "When a liquid changes to a gas it ___."

Answer: evaporates — not in word bank.

But "gas" is in the word bank.

Again, if the sentence is:

> "When a liquid changes to a gas it becomes a ___."

Then answer: gas

Similarly, for Q1:
> "When a solid changes to a liquid it becomes a ___." → liquid

That makes sense!

And the word bank has: solid, liquid, gas, heat, cold, condensation

So likely:

---

Final Interpretation:

The worksheet is asking students to identify the new state after a phase change.

#### Question 1:
Diagram: Solid → Liquid
Sentence: When a solid changes to a liquid it becomes a ___.

✔ Answer: liquid

#### Question 2:
Diagram: Liquid → Gas
Sentence: When a liquid changes to a gas it becomes a ___.

✔ Answer: gas

Then the word bank includes:
- solid
- liquid
- gas
- heat
- cold
- condensation

So both answers come from the word bank.

Also, the note:
> "Adding heat gives things (increased) energy."

This explains why phase changes happen — heat provides energy to break bonds.

---

Additional Notes:

- Condensation: Gas → Liquid (e.g., steam turning to water)
- Heat: Required for melting and evaporation
- Cold: Causes freezing and condensation

So if there were a third question about gas → liquid, the answer might be condensation.

But based on the two diagrams shown (solid → liquid, liquid → gas), the most logical answers are:

---

✔ Answers:

1. When a solid changes to a liquid it becomes a liquid.
2. When a liquid changes to a gas it becomes a gas.

---

Explanation:

- Melting: Solid → Liquid (requires heat)
- Evaporation: Liquid → Gas (requires heat)
- The word bank provides the names of the states: solid, liquid, gas
- The processes (like melting, evaporation) are not in the bank, but the resulting state is.

So the worksheet is teaching students to identify the final state after a phase change.

---

Summary:

| Question | Diagram | Answer |
|--------|--------|--------|
| 1 | Solid → Liquid | liquid |
| 2 | Liquid → Gas | gas |

✔ Use the word bank to fill in the blank with the name of the new state.

If your worksheet has different wording, please clarify, but this is the most logical solution based on standard educational materials.
