Worksheet on the properties of solids, liquids, and gases, featuring a table with key characteristics like particle arrangement and energy.

To solve this worksheet, we need to sort the phrases into three groups: Solids, Liquids, and Gases. We’ll look at how particles behave in each state — their energy, how they move, how much space is between them, and whether they have a fixed shape or volume.

Let’s go step by step.

---

Step 1: Understand the key differences

- Solids:
- Particles are tightly packed (very little space between them).
- Strong bonds hold them in place.
- They don’t flow easily.
- Have low energy.
- Fixed shape and fixed volume.

- Liquids:
- Particles are close but can slide past each other.
- Some space between particles.
- Weak bonds (but not very weak).
- Flow easily (but not as much as gases).
- Take the shape of container, but volume stays the same.
- Medium energy.

- Gases:
- Lots of space between particles.
- Very weak bonds (almost none).
- Flow very easily.
- High or very high energy.
- Spread out to fill container — both shape and volume change.

---

Step 2: Go through each phrase and assign it

We’ll list all phrases and match them:

1. have a fixed shape → Solid
2. particles are linked by weak bonds → Liquid (gases have *very* weak bonds)
3. lots of space between the particles → Gas
4. particles flow easily → Could be liquid or gas — but “flow easily” is more typical of liquids; gases “spread out” or “flow very easily”. Let’s hold.
5. particles do not flow easily → Solid
6. particles have high energy → Gas (or very high for gas, high might be liquid? Wait — let’s check standard teaching: solids = low, liquids = medium, gases = high/very high)
Actually, many curricula say:
- Solid: low energy
- Liquid: medium energy
- Gas: high or very high energy
So “high energy” → Gas
“very high energy” → also Gas
7. take the shape of a container → Liquid (and gas, but gas also spreads out — this phrase usually means liquid)
8. very little space between the particles → Solid
9. particles are linked by very weak bonds → Gas
10. particles have very high energy → Gas
11. some space between the particles → Liquid
12. the space they take up stays the same → Solid and Liquid (both have fixed volume)
13. the space they take up stays the same (again) → Solid and Liquid
14. the space they take up can change → Gas
15. particles are linked by strong bonds → Solid
16. particles have low energy → Solid
17. spread out inside a container → Gas
18. particles flow easily (again) → This one appears twice — likely meant for liquid and gas? But let’s see context.

Wait — there are duplicates? Let me recount the grid.

Looking back at the image description, there are 18 boxes arranged in 6 rows x 3 columns.

List again clearly:

Row 1:
- have a fixed shape → Solid
- particles are linked by weak bonds → Liquid
- lots of space between the particles → Gas

Row 2:
- particles flow easily → Liquid (or Gas? But “flow easily” is often used for liquids; gases “expand” or “move freely”)
- particles do not flow easily → Solid
- particles have high energy → Gas

Row 3:
- take the shape of a container → Liquid
- very little space between the particles → Solid
- particles are linked by very weak bonds → Gas

Row 4:
- particles have very high energy → Gas
- some space between the particles → Liquid
- the space they take up stays the same → Solid or Liquid (volume fixed)

Row 5:
- the space they take up stays the same → Solid or Liquid
- the space they take up can change → Gas
- particles are linked by strong bonds → Solid

Row 6:
- particles have low energy → Solid
- spread out inside a container → Gas
- particles flow easily → Again? Probably meant for liquid — maybe duplicate error? Or perhaps one is for liquid, one for gas? But “flow easily” is ambiguous.

Actually, in many worksheets, “particles flow easily” is assigned to liquids, and “spread out” or “move freely” to gases.

Also, note: “the space they take up stays the same” appears twice — that’s fine, because both solids and liquids have fixed volume.

Similarly, “particles flow easily” appears twice — probably one is for liquid, and maybe the other is a mistake? Or perhaps intended for gas? But gas doesn’t just “flow” — it expands.

Let’s use standard classification:

Assign each phrase to the best fit:

Solids:
- have a fixed shape
- particles do not flow easily
- very little space between the particles
- particles are linked by strong bonds
- particles have low energy
- the space they take up stays the same (first instance)
→ That’s 6 phrases.

Liquids:
- particles are linked by weak bonds
- particles flow easily (first occurrence)
- take the shape of a container
- some space between the particles
- the space they take up stays the same (second instance)
→ That’s 5 phrases. Need one more.

Wait — total phrases: 18. If solids = 6, gases = 6, then liquids = 6.

What’s missing for liquids?

Look again: “particles flow easily” appears twice — maybe one is for liquid, one for gas? But that’s not accurate.

Alternatively, perhaps “particles flow easily” is only for liquid, and the second one is a duplicate by mistake? Or maybe in this worksheet, they consider “flow easily” for both? Unlikely.

Another possibility: “the space they take up stays the same” is for both solid and liquid — so we can assign it to both categories? But the worksheet likely expects each phrase to be used once per category.

Wait — actually, looking at the layout, it’s probably a cut-and-paste activity where you sort the phrases into three columns: Solid, Liquid, Gas.

So we need to assign each of the 18 phrases to one of the three states.

Let’s make a clean list:

Phrases:

A. have a fixed shape → Solid
B. particles are linked by weak bonds → Liquid
C. lots of space between the particles → Gas
D. particles flow easily → Liquid (commonly taught)
E. particles do not flow easily → Solid
F. particles have high energy → Gas
G. take the shape of a container → Liquid
H. very little space between the particles → Solid
I. particles are linked by very weak bonds → Gas
J. particles have very high energy → Gas
K. some space between the particles → Liquid
L. the space they take up stays the same → Solid or Liquid (let’s assign to Liquid for now)
M. the space they take up stays the same → Solid (since solid definitely has fixed volume)
N. the space they take up can change → Gas
O. particles are linked by strong bonds → Solid
P. particles have low energy → Solid
Q. spread out inside a container → Gas
R. particles flow easily → This is duplicate — perhaps it’s meant to be for gas? But “flow easily” isn’t ideal for gas. Maybe it’s a typo, and it should be “move freely” or something. In many sources, “particles flow easily” is for liquids.

But we have 18 phrases. Let’s count assignments:

Solids: A, E, H, O, P, M → 6
Liquids: B, D, G, K, L → 5 — need one more
Gases: C, F, I, J, N, Q → 6

Missing one for liquids. What about the second “particles flow easily”? If we assign it to liquids, that makes 6.

But why is it listed twice? Perhaps it’s intentional — maybe one is for liquid and one for gas? But that would be incorrect.

Alternative: perhaps “particles flow easily” is for liquids, and the other instance is a mistake in my reading.

Looking back at the user’s description:

In row 2, column 1: “particles flow easily”
In row 6, column 3: “particles flow easily” — yes, duplicate.

In educational materials, sometimes duplicates occur by error, but here it might be that one is for liquid and one for gas? But that doesn’t make sense.

Perhaps for gas, it’s “spread out”, and “flow easily” is only for liquid.

Another idea: maybe “particles flow easily” is meant for both liquid and gas, but we have to choose based on context.

Let’s think differently. Let’s group by property.

Final decision based on standard science curriculum:

Solid Properties:
- have a fixed shape
- particles do not flow easily
- very little space between the particles
- particles are linked by strong bonds
- particles have low energy
- the space they take up stays the same (we’ll use one instance)

Liquid Properties:
- particles are linked by weak bonds
- particles flow easily (use one instance)
- take the shape of a container
- some space between the particles
- the space they take up stays the same (use the other instance)
- ??? We need a sixth.

What about “particles have medium energy”? Not listed. Or perhaps “flow easily” is sufficient.

Wait — in row 4, column 3: “the space they take up stays the same” — we can assign this to liquid.

And in row 5, column 1: “the space they take up stays the same” — assign to solid.

That works.

Now for the duplicate “particles flow easily”: perhaps it’s a error, or perhaps in this worksheet, they want it for liquid only, and the second one is redundant.

But to have 6 for each, let’s assign the second “particles flow easily” to gas? No, that’s not accurate.

Another phrase: in row 2, column 3: “particles have high energy” — we assigned to gas.

But “very high energy” is also gas.

Perhaps “particles have high energy” is for liquid? Some curricula say liquids have higher energy than solids but lower than gases.

Let’s check a reliable source mentally:

Typical particle model:

- Solid: low kinetic energy, vibrate in place
- Liquid: medium kinetic energy, slide past each other
- Gas: high kinetic energy, move rapidly and freely

So “high energy” could be gas, “very high” also gas — but perhaps “high” is for liquid? No, usually “high” is gas.

Perhaps “particles have high energy” is for gas, and “very high” is also gas, but we can use both for gas.

For liquids, we have:

- weak bonds
- flow easily
- take shape of container
- some space
- fixed volume (space stays same)
- and what else?

Ah! In row 4, column 2: “some space between the particles” — that’s liquid.

Row 3, column 1: “take the shape of a container” — liquid.

Row 1, column 2: “weak bonds” — liquid.

Row 2, column 1: “flow easily” — liquid.

Row 5, column 1: “space stays same” — liquid.

That’s 5. Need one more.

What about “particles have medium energy”? Not listed.

Perhaps “the space they take up stays the same” is for both, but we have two instances.

Another idea: in row 6, column 1: “particles have low energy” — solid.

Row 6, column 2: “spread out inside a container” — gas.

Row 6, column 3: “particles flow easily” — if we assign to liquid, then liquids have 6.

But why is it listed twice? Perhaps it’s a mistake in the worksheet, or perhaps for this exercise, we can use it for liquid twice? No.

Let’s list all 18 and assign:

1. have a fixed shape → Solid
2. particles are linked by weak bonds → Liquid
3. lots of space between the particles → Gas
4. particles flow easily → Liquid
5. particles do not flow easily → Solid
6. particles have high energy → Gas
7. take the shape of a container → Liquid
8. very little space between the particles → Solid
9. particles are linked by very weak bonds → Gas
10. particles have very high energy → Gas
11. some space between the particles → Liquid
12. the space they take up stays the same → Solid (first instance)
13. the space they take up stays the same → Liquid (second instance)
14. the space they take up can change → Gas
15. particles are linked by strong bonds → Solid
16. particles have low energy → Solid
17. spread out inside a container → Gas
18. particles flow easily → This is the duplicate. Since we already have one for liquid, and gases don't "flow easily" in the same way, perhaps this is meant for gas? But that's not accurate. Maybe it's a error, and we should assign it to liquid again, but that would make 7 for liquid.

Perhaps "particles flow easily" is for liquids, and the other instance is for gases, but in some contexts, gases flow.

In physics, gases do flow, but in particle theory worksheets, "flow easily" is typically for liquids, and "spread out" or "move freely" for gases.

Given that, and to have 6 per category, let's assign the second "particles flow easily" to gas, even though it's not perfect.

But let's see the counts:

If we do:

Solids: 1,5,8,12,15,16 → 6
Liquids: 2,4,7,11,13,18 → 6 (using the second "flow easily" for liquid)
Gases: 3,6,9,10,14,17 → 6

Yes, that works. And "particles flow easily" can be interpreted as liquids flowing, and perhaps the duplicate is for emphasis or error, but we'll use it for liquid.

Some might argue that "flow easily" is for both, but in this case, it's fine.

So final assignment:

Solid:
- have a fixed shape
- particles do not flow easily
- very little space between the particles
- the space they take up stays the same (first)
- particles are linked by strong bonds
- particles have low energy

Liquid:
- particles are linked by weak bonds
- particles flow easily (first)
- take the shape of a container
- some space between the particles
- the space they take up stays the same (second)
- particles flow easily (second) — but this is redundant; perhaps it's better to have only one, but since it's listed, we'll include it.

To avoid redundancy, perhaps the worksheet intends "particles flow easily" only for liquid, and the other is a mistake. But for the sake of completing, we'll assign as above.

Another way: perhaps "particles flow easily" is for liquids, and for gases, it's "spread out", so the second "flow easily" might be a typo, but we have to use it.

I think for accuracy, let's assign:

After reevaluation, in many standard worksheets, the properties are:

For Solids:
- fixed shape
- fixed volume
- particles close together
- strong bonds
- low energy
- do not flow

For Liquids:
- no fixed shape (take container shape)
- fixed volume
- particles close but can move
- weak bonds
- medium energy
- flow easily

For Gases:
- no fixed shape
- no fixed volume (expand to fill)
- particles far apart
- very weak bonds
- high energy
- flow very easily or spread out

So "particles flow easily" is for liquids, and "spread out" for gases.

The duplicate "particles flow easily" might be an error, but since it's there, and to have 6 each, we can assign one to liquid and one to gas, but that's not ideal.

Perhaps "particles flow easily" is for liquids, and the other instance is meant to be "particles move freely" or something, but as given, we'll proceed.

Let's finalize with:

Solid Properties:
1. have a fixed shape
2. particles do not flow easily
3. very little space between the particles
4. the space they take up stays the same (we'll use this for solid)
5. particles are linked by strong bonds
6. particles have low energy

Liquid Properties:
1. particles are linked by weak bonds
2. particles flow easily (first occurrence)
3. take the shape of a container
4. some space between the particles
5. the space they take up stays the same (second occurrence)
6. [missing] — what about "particles have medium energy"? Not listed. Perhaps "flow easily" is sufficient, but we have another "flow easily".

I think the best is to assign the second "particles flow easily" to liquid, making it 6, even though it's duplicate.

For gases:
1. lots of space between the particles
2. particles have high energy
3. particles are linked by very weak bonds
4. particles have very high energy
5. the space they take up can change
6. spread out inside a container

That's 6 for gases.

For liquids, if we use both "flow easily", it's 6.

So:

Liquid:
- particles are linked by weak bonds
- particles flow easily (row2,col1)
- take the shape of a container
- some space between the particles
- the space they take up stays the same (row4,col3)
- particles flow easily (row6,col3) — but this is the same phrase.

Perhaps in the worksheet, it's intentional to have two, but for sorting, we can put both in liquid.

To resolve, let's assume that "particles flow easily" is for liquids, and the duplicate is a mistake, but since the task is to sort, we'll include it.

Final decision:

After careful thought, here is the correct sorting based on standard science education:

Solids:
- have a fixed shape
- particles do not flow easily
- very little space between the particles
- the space they take up stays the same (first instance)
- particles are linked by strong bonds
- particles have low energy

Liquids:
- particles are linked by weak bonds
- particles flow easily (first instance)
- take the shape of a container
- some space between the particles
- the space they take up stays the same (second instance)
- [and the second "particles flow easily" is likely a error, but if must, assign to liquid]

But to have exactly 6, and since "particles flow easily" is listed twice, perhaps one is for liquid and one for gas, but that's not accurate.

Another possibility: in some curricula, "particles flow easily" is for both liquid and gas, but gas is "very easily".

I recall that in some worksheets, "flow" is used for liquids, and "expand" for gases.

Let's look for a different approach.

Perhaps "the space they take up stays the same" is for both solid and liquid, so we can assign one to each.

Similarly, "particles flow easily" might be intended for liquid only, and the second instance is for gas, but let's calculate the number.

Total phrases: 18.

If we assign:

Solid: 6 phrases
Liquid: 6 phrases
Gas: 6 phrases

From the list:

Phrases that are unambiguously solid:
- have a fixed shape
- particles do not flow easily
- very little space between the particles
- particles are linked by strong bonds
- particles have low energy
- the space they take up stays the same (use one)

That's 6.

Unambiguously gas:
- lots of space between the particles
- particles have high energy
- particles are linked by very weak bonds
- particles have very high energy
- the space they take up can change
- spread out inside a container

That's 6.

Then liquids must be the remaining 6:
- particles are linked by weak bonds
- particles flow easily (first)
- take the shape of a container
- some space between the particles
- the space they take up stays the same (second)
- particles flow easily (second) — so both "flow easily" go to liquid.

Even though it's duplicate, for the purpose of this worksheet, we'll assign both to liquid.

So the sorted groups are:

Solid:
- have a fixed shape
- particles do not flow easily
- very little space between the particles
- the space they take up stays the same
- particles are linked by strong bonds
- particles have low energy

Liquid:
- particles are linked by weak bonds
- particles flow easily
- take the shape of a container
- some space between the particles
- the space they take up stays the same
- particles flow easily (duplicate, but included)

Gas:
- lots of space between the particles
- particles have high energy
- particles are linked by very weak bonds
- particles have very high energy
- the space they take up can change
- spread out inside a container

Note: "the space they take up stays the same" is used for both solid and liquid, which is correct, as both have fixed volume.

"Particles flow easily" is used twice for liquid, which might be a worksheet error, but based on the given phrases, this is the only way to have 6 per category.

In reality, "particles flow easily" should only be for liquid once, and the duplicate might be a mistake, but for this task, we'll proceed.

So the final answer is the sorted groups.

Since the user didn't specify how to present the answer, but typically for such worksheets, you sort the phrases into three columns.

So I'll provide the sorted lists.

Final Answer:

Solid Properties:
- have a fixed shape
- particles do not flow easily
- very little space between the particles
- the space they take up stays the same
- particles are linked by strong bonds
- particles have low energy

Liquid Properties:
- particles are linked by weak bonds
- particles flow easily
- take the shape of a container
- some space between the particles
- the space they take up stays the same
- particles flow easily

Gas Properties:
- lots of space between the particles
- particles have high energy
- particles are linked by very weak bonds
- particles have very high energy
- the space they take up can change
- spread out inside a container

Note: "the space they take up stays the same" appears in both Solid and Liquid, which is correct. "Particles flow easily" appears twice in Liquid, which may be a worksheet duplication, but based on the given phrases, this is the accurate sorting.
