Exercise Phase Change diagram with drag-and-drop labels for states of matter and phase transitions.

Let’s solve this step by step.

We have three states of matter shown in the diagram:

1. Left box: Molecules are tightly packed in a regular array and move very little → This is Solid.
2. Middle box: Molecules are close together but move relative to each other → This is Liquid.
3. Right box: Molecules are far apart and fill the available place → This is Gas.

Now, we need to label the phase changes (the yellow boxes with arrows).

Phase changes between solid, liquid, and gas:

- Solid → Liquid = Melting
- Liquid → Solid = Freezing
- Liquid → Gas = Vaporisation
- Gas → Liquid = Condensation
- Solid → Gas = Sublimation
- Gas → Solid = Deposition

Looking at the diagram:

Top middle (liquid) ↔ Left (solid):
→ Arrow from solid to liquid: Melting
→ Arrow from liquid to solid: Freezing

Top middle (liquid) ↔ Right (gas):
→ Arrow from liquid to gas: Vaporisation
→ Arrow from gas to liquid: Condensation

Left (solid) ↔ Right (gas):
→ Arrow from solid to gas: Sublimation
→ Arrow from gas to solid: Deposition

Also, we must label the blue boxes under each state:

- Under left image (tightly packed): Solid
- Under middle image (close but moving): Liquid
- Under right image (far apart): Gas

So now, let’s assign all labels correctly based on positions:

Blue boxes (states of matter):

- Bottom-left blue box → Solid
- Middle-bottom blue box → Liquid
- Bottom-right blue box → Gas

Yellow boxes (phase changes):

There are 6 yellow boxes total — 3 pairs of opposite arrows.

From left (solid) to middle (liquid): upward arrow → Melting
From middle (liquid) to left (solid): downward arrow → Freezing

From middle (liquid) to right (gas): upward arrow → Vaporisation
From right (gas) to middle (liquid): downward arrow → Condensation

From left (solid) to right (gas): diagonal up-right arrow → Sublimation
From right (gas) to left (solid): diagonal down-left arrow → Deposition

Wait — looking again at the diagram layout:

Actually, the diagram has:

- Top center: Liquid (with description)
- Bottom left: Solid
- Bottom right: Gas

Arrows:

Between Solid and Liquid: two arrows (up and down) → Melting (solid→liquid), Freezing (liquid→solid)

Between Liquid and Gas: two arrows (up and down) → Vaporisation (liquid→gas), Condensation (gas→liquid)

Between Solid and Gas: two diagonal arrows → Sublimation (solid→gas), Deposition (gas→solid)

In the diagram, the yellow boxes are placed along these arrows.

Specifically:

- From Solid (left) to Liquid (top): yellow box above the arrow → should be Melting
- From Liquid (top) to Solid (left): yellow box below that same pair → should be Freezing

Similarly:

- From Liquid (top) to Gas (right): yellow box above → Vaporisation
- From Gas (right) to Liquid (top): yellow box below → Condensation

And diagonally:

- From Solid (left) to Gas (right): yellow box on upper diagonal → Sublimation
- From Gas (right) to Solid (left): yellow box on lower diagonal → Deposition

But wait — in the actual diagram, there are only 6 yellow boxes? Let me count:

Actually, looking at the structure:

There are 3 sets of double-headed arrows:

1. Between Solid and Liquid → 2 yellow boxes (one for each direction)
2. Between Liquid and Gas → 2 yellow boxes
3. Between Solid and Gas → 2 yellow boxes

Total 6 yellow boxes.

And 3 blue boxes for the states.

The instruction says: “Drag and Drop the correct answer to the box in the above diagram”

Available options:

States: Solid, Liquid, Gas
Processes: Sublimation, Melting, Deposition, Freezing, Vaporisation, Condensation

That’s exactly 9 items — matches 3 blue + 6 yellow boxes.

So final assignment:

Blue boxes (under images):

- Left image (tightly packed) → Solid
- Middle image (close but moving) → Liquid
- Right image (far apart) → Gas

Yellow boxes (along arrows):

Assuming standard orientation:

Arrow from Solid → Liquid (upward or rightward?) — in diagram, it's likely:

From left (solid) to top (liquid): arrow going up-right → yellow box on that path → Melting

From top (liquid) to left (solid): arrow going down-left → yellow box → Freezing

From top (liquid) to right (gas): arrow going down-right → yellow box → Vaporisation

From right (gas) to top (liquid): arrow going up-left → yellow box → Condensation

From left (solid) to right (gas): direct diagonal? Actually, in many diagrams, solid-gas is shown as crossing, but here it might be implied via the outer arrows.

Wait — re-examining the original diagram description:

It shows:

- Center-top: Liquid
- Bottom-left: Solid
- Bottom-right: Gas

With bidirectional arrows between each pair.

So:

Between Solid and Liquid: two arrows → label them Melting (S→L) and Freezing (L→S)

Between Liquid and Gas: two arrows → Vaporisation (L→G) and Condensation (G→L)

Between Solid and Gas: two arrows → Sublimation (S→G) and Deposition (G→S)

In the diagram, the yellow boxes are positioned along those arrows.

Typically, in such diagrams:

- The arrow pointing from solid to liquid is labeled "Melting"
- The reverse is "Freezing"
- Liquid to gas: "Vaporisation"
- Gas to liquid: "Condensation"
- Solid to gas: "Sublimation"
- Gas to solid: "Deposition"

Now, to match the exact positions in the diagram (even though I can’t see it, based on standard layout):

Usually:

- The horizontal or near-horizontal arrow from left (solid) to center (liquid) → Melting
- Reverse → Freezing
- From center (liquid) to right (gas) → Vaporisation
- Reverse → Condensation
- Diagonal from left (solid) to right (gas) → Sublimation
- Reverse → Deposition

But in some layouts, the solid-gas connection is not direct; however, the problem includes both sublimation and deposition, so they must be used.

Given that, and since the user will drag and drop, we just need to assign correctly.

Final mapping:

Blue boxes (state names under each particle diagram):

- Under left diagram (tightly packed): Solid
- Under middle diagram (close but moving): Liquid
- Under right diagram (far apart): Gas

Yellow boxes (processes on arrows):

Assume:

- Arrow from Solid to Liquid → Melting
- Arrow from Liquid to Solid → Freezing
- Arrow from Liquid to Gas → Vaporisation
- Arrow from Gas to Liquid → Condensation
- Arrow from Solid to Gas → Sublimation
- Arrow from Gas to Solid → Deposition

This is standard and matches all given terms.

Therefore, the correct answers to drag and drop are:

For blue boxes:
- Left: Solid
- Middle: Liquid
- Right: Gas

For yellow boxes (depending on arrow direction, but since the diagram has specific placements, and assuming conventional labeling):

But since the question doesn't specify which yellow box is which visually, and we have to provide the final answer as per the task, perhaps we list all assignments.

However, the instruction is to “drag and drop the correct answer to the box”, implying we identify what goes where.

Since I can't interact, I’ll provide the complete set of correct labels for each position based on standard interpretation.

But to give a clear final answer, perhaps list:

The three blue boxes (from left to right under the diagrams): Solid, Liquid, Gas

The six yellow boxes: typically arranged as:

- Between solid and liquid: Melting (on S→L arrow), Freezing (on L→S arrow)
- Between liquid and gas: Vaporisation (on L→G arrow), Condensation (on G→L arrow)
- Between solid and gas: Sublimation (on S→G arrow), Deposition (on G→S arrow)

In many textbook diagrams, the arrows are drawn such that:

- Upward/rightward arrows for endothermic processes (melting, vaporisation, sublimation)
- Downward/leftward for exothermic (freezing, condensation, deposition)

But without seeing the exact arrow directions in the image, we rely on standard convention.

Given that, and since the problem is standard, the answer is straightforward.

Final Answer:

Blue boxes (under particle diagrams, left to right):
Solid, Liquid, Gas

Yellow boxes (phase change processes):
- Solid to Liquid: Melting
- Liquid to Solid: Freezing
- Liquid to Gas: Vaporisation
- Gas to Liquid: Condensation
- Solid to Gas: Sublimation
- Gas to Solid: Deposition

To present it cleanly for drag-and-drop:

Assign:

- Blue box under left image: Solid
- Blue box under middle image: Liquid
- Blue box under right image: Gas

- Yellow box on arrow from solid to liquid: Melting
- Yellow box on arrow from liquid to solid: Freezing
- Yellow box on arrow from liquid to gas: Vaporisation
- Yellow box on arrow from gas to liquid: Condensation
- Yellow box on arrow from solid to gas: Sublimation
- Yellow box on arrow from gas to solid: Deposition

This uses all provided terms correctly.

Final Answer:
Blue boxes: Left - Solid, Middle - Liquid, Right - Gas
Yellow boxes: Solid→Liquid - Melting, Liquid→Solid - Freezing, Liquid→Gas - Vaporisation, Gas→Liquid - Condensation, Solid→Gas - Sublimation, Gas→Solid - Deposition
