Accepted Answer

To solve this matching problem, we analyze each question and match it with the correct term based on the definitions:

### Question 13
The saltiness of seawater relates to what it is made of (salts dissolved in water).
- **Term**: b. composition (composition refers to what makes up a substance and how it is arranged).

### Question 14
Objects float or sink based on how much mass they have per unit volume (a measure of density).
- **Term**: j. density (density determines buoyancy: if an object’s density is less than the fluid, it floats; otherwise, it sinks).

### Question 15
The physical form (solid, liquid, gas, etc.) of a substance is its state of matter.
- **Term**: e. state of matter (state of matter describes the physical form a substance exists in).

### Question 16
The type of matter (and its arrangement) that makes up an object is its composition. Wait, no—wait, “type of matter and arrangement” is also composition? Wait, no, recheck: “This type of matter makes up an object and the way it is arranged” – this is **composition** (what the object is made of and how it is structured). Wait, but let’s confirm:
- **Term**: b. composition (composition includes the type of matter and its arrangement). Wait, but question 13 also used “composition”? Wait, no, maybe I made a mistake. Wait, question 13: “saltiness of seawater is the result of this property” – saltiness is about what’s in the water (composition). Question 16: “type of matter makes up an object and the way it is arranged” – that’s also composition? Wait, maybe the terms are reused? No, the problem says “some terms will not be used”, so maybe I misread. Wait, no—wait, question 16: “This type of matter makes up an object and the way it is arranged” – actually, “composition” is the correct term here (what the object is composed of, including the type of matter and its arrangement). Wait, but question 13 is also composition? That can’t be. Wait, no—wait, question 13: saltiness is due to the **composition** (salts in water). Question 16: “type of matter and arrangement” is also composition. Maybe the problem has a typo, but based on definitions:
- Question 16: b. composition (matches “type of matter and arrangement”).

### Question 17
The breakdown of water into gases (hydrogen and oxygen) via electricity is **electrolysis**.
- **Term**: h. electrolysis (electrolysis is the process of using electricity to decompose a compound, like water).

### Question 18
The ability to resist burning is **nonflammability**.
- **Term**: c. nonflammability (nonflammable substances resist burning).

### Question 19
The tendency to resist changes in motion is **inertia** (Newton’s first law: inertia is the resistance to changes in velocity).
- **Term**: d. inertia

### Question 20
The rate at which a substance conducts heat is **thermal conductivity**.
- **Term**: a. thermal conductivity (thermal conductivity measures heat transfer through a substance).

### Final Matches:
13. $\boldsymbol{b}$
14. $\boldsymbol{j}$
15. $\boldsymbol{e}$
16. $\boldsymbol{b}$ (Wait, no—this must be an error. Wait, recheck question 16: “This type of matter makes up an object and the way it is arranged” – maybe “composition” is correct, but question 13 is also composition? Alternatively, maybe I misread question 16. Wait, maybe question 16 is “This type of matter makes up an object and the way it is arranged” – actually, “composition” is correct, but perhaps the problem has a duplicate. Alternatively, maybe question 16 is “structure” but no, the terms given: let’s re-express:

Wait, let’s re-express each term:

- a. thermal conductivity: heat conduction rate
- b. composition: what a substance is made of (type of matter + arrangement)
- c. nonflammability: resists burning
- d. inertia: resists motion change
- e. state of matter: solid/liquid/gas
- f. solubility: ability to dissolve
- g. reactivity: tendency to react
- h. electrolysis: process of decomposing with electricity
- i. ductility: ability to be drawn into wires
- j. density: mass/volume (buoyancy)

So:

13. Saltiness of seawater: due to **composition** (salts in water) → b
14. Float/sink: **density** → j
15. Physical form: **state of matter** → e
16. Type of matter + arrangement: **composition** → b (even if repeated, the problem says “some terms will not be used”, so maybe composition is used twice)
17. Breakdown of water (via electricity): **electrolysis** → h
18. Resist burning: **nonflammability** → c
19. Resist motion change: **inertia** → d
20. Heat conduction rate: **thermal conductivity** → a
