Chemistry worksheet comparing mass, volume, and density of matter particles in different containers.

Let’s go step by step to solve this worksheet.

Part 1: Figure 1 — Comparing Objects A and B

We are told:
- Each dot = one particle of matter.
- Particles are evenly spread out in each box.
- All particles have the same mass.

So:
→ More particles = more total mass.
→ Bigger box (more space) = bigger volume.
→ Density = mass ÷ volume → if particles are spaced the same way, density is the same.

Looking at Figure 1:
- Object A: small box, fewer dots (let’s count: 2 rows × 4 columns = 8 particles)
- Object B: taller box, more dots (3 rows × 5 columns = 15 particles? Wait — actually looking again: it looks like 3 rows of 6 = 18? But exact count isn’t needed — we just need to compare.)

Actually, from the handwritten answers already on the page, they say:

Mass: A < B → because B has more particles → correct.

Volume: A < B → because B’s box is bigger → correct.

Density: A = B → because particles are distributed the same way (same spacing) → so even though B has more mass and more volume, the ratio (density) is the same → correct.

So for Part 1, the completed table is:

| Property | Relationship | Reasoning |
|----------|--------------|-----------|
| Mass | A < B | B has more particles, so more mass |
| Volume | A < B | B has larger dimensions of box |
| Density | A = B | Particles in A and B are distributed the same way, so density is the same |

Part 2: Figure 2 — Comparing Objects A, B, and C

Again:
- Same rules: each dot = same mass, evenly distributed.

From Figure 2:
- Object A: medium-sized box, some particles (say 2x4 = 8)
- Object B: taller box, more particles than A (looks like 3x5 = 15?) → but again, relative comparison matters.
- Object C: same size as A? Or similar? Actually, C looks same size as A but has more particles packed in → so higher density.

Handwritten answers on the page:

Mass:
- A < B → because B has more particles → correct.
- A < C → because C has more particles than A (even though same volume) → correct.

Volume:
- A < B → B is bigger → correct.
- A = C → same size boxes → correct.

Density:
- A = B → wait, is that right? Let’s check.

Wait — if A and B have different volumes and different masses, but particles are spaced the same way? Looking at Figure 2:

Actually, in Figure 2, A and B appear to have the same particle spacing — meaning same density. Even though B is bigger and has more mass, the particles per unit volume are the same → so density equal → correct.

But C: same volume as A, but more particles → so higher density → A < C → correct.

So final table for Part 2:

| Property | Relationship | Reasoning |
|----------|--------------|-----------|
| Mass | A < B | B is larger than A, more particles → more mass |
| | A < C | In C there are more particles than in A |
| Volume | A < B | B is bigger than A |
| | A = C | Same volume |
| Density | A = B | A and B have the same distribution (spacing) |
| | A < C | C has more particles than A in the same volume |

All handwritten answers on the worksheet are correct.

Final Answer:
The completed tables are accurate as written in the worksheet. For Figure 1: Mass A < B, Volume A < B, Density A = B. For Figure 2: Mass A < B and A < C, Volume A < B and A = C, Density A = B and A < C. All reasoning provided is correct.
