## ✔ SOLUTION TO “QUIZ: THE PROPERTIES OF MATTER”

1. Matching (10 points)

Match each description with the correct property from the word bank:

Word Bank:
A) boiling point
B) color
C) conductivity
D) density
E) ductility
F) elasticity
G) flammability
H) luster
I) malleability
J) magnetism
K) odor
L) reactivity
M) solubility
N) taste
O) viscosity

---

Answers:

1. Lusters are more shiny than others. → H) luster
*(Luster describes how shiny a material is.)*

2. It takes time to see how much weight an object has. → D) density
*(Density = mass/volume — it’s about how much mass is packed into a volume, which relates to “weight per size.”)*

3. Copper can be stretched into thin wires and is often used for electrical wiring. → E) ductility
*(Ductility = ability to be drawn into wires.)*

4. At room temperature, mercury is the only metal found as a liquid. → A) boiling point *(or possibly melting point — but since it says “room temp liquid,” it implies low melting point. However, “boiling point” is listed, and sometimes worksheets use it loosely. But technically, this should be melting point. Since it’s not in the bank, we assume they mean phase change temp — best fit is A.)*
→ A) boiling point *(Note: Strictly speaking, this describes melting point, but if only boiling point is available, it’s the closest match.)*

5. When painting with oils, the oil cannot be removed by water, but it will mix with paint thinner. → M) solubility
*(Solubility = ability of a substance to dissolve in another. Oils are soluble in organic solvents like paint thinner, not water.)*

6. Dry wood catches fire easily when heated. → G) flammability
*(Flammability = how easily something catches fire.)*

7. Hydrochloric acid reacts with zinc to produce hydrogen gas. → L) reactivity
*(Reactivity = how readily a substance undergoes chemical reaction.)*

8. Aluminum foil is easily shaped into pie plates. → I) malleability
*(Malleability = ability to be hammered or rolled into thin sheets.)*

9. My shirt isn’t soft, but my dog’s fur is. → F) elasticity *(Wait — this is tricky. “Softness” isn’t directly in the list. But “elasticity” refers to stretchiness. Maybe the intent was texture? However, none of the options perfectly fit “softness.” Let’s reconsider: perhaps it’s implying flexibility or texture — but among options, F is closest if we interpret “soft” as flexible. Alternatively, it might be a trick — but since “elasticity” is the only one related to physical deformation, we’ll go with F.)*
→ F) elasticity *(Best available choice, though imperfect.)*

10. Sugar can dissolve in water while other substances cannot. → M) solubility
*(Same as #5 — sugar dissolves in water = solubility.)*

11. When using bleach on a mechanical pencil, it stains more easily than using ink. → K) odor *(This doesn’t make sense chemically — bleach doesn’t stain, it bleaches. Probably a typo. If it’s about smell, then K. If about staining, maybe color? But “stains more easily” suggests reactivity or color change. Since “reactivity” is already used, and “color” is B, perhaps B? But bleach removes color. This question is flawed. Best guess: if it’s about smell after using bleach, then K. Otherwise, likely B or L. Given ambiguity, we’ll say K) odor — assuming it’s about the smell of bleach.)*
→ K) odor *(Assumed intent — bleach has strong odor.)*

12. An example of a sample of aluminum from the same source, but reaches the same temperature at different times. → D) density *(This is confusing. If samples are from same source, they should have same density. Maybe it’s about heat capacity? Not in word bank. Perhaps it’s misphrased. Best fit: D) density — since density is intrinsic and doesn’t change with sample size or heating rate.)*
→ D) density *(Intrinsic property — same regardless of sample size or heating.)*

13. A sample of gold from a mine in South Africa has the same color as gold from Alaska. → B) color
*(Color is a physical property that remains consistent for pure elements.)*

2. Describe ONE difference between a physical property and a chemical property. (3 points)

> Physical property can be observed or measured without changing the substance’s chemical identity (e.g., color, density, melting point).
> Chemical property describes how a substance reacts or changes into a new substance (e.g., flammability, reactivity with acid).

✔ Sample Answer:
*A physical property, like color or density, can be observed without altering the substance’s composition. A chemical property, like flammability, describes how a substance behaves during a chemical reaction and results in a new substance.*

3. Define the following properties of matter: (3 points)

a) electrical conductivity
→ *The ability of a material to allow electric current to flow through it. Metals like copper are good conductors.*

b) boiling point
→ *The temperature at which a liquid turns into a gas (vapor) at a given pressure (usually atmospheric pressure). For water, it’s 100°C.*

c) viscosity
→ *A measure of a fluid’s resistance to flow. Honey has high viscosity; water has low viscosity.*

## 📝 Final Notes:

- This quiz tests understanding of physical vs. chemical properties and common material properties.
- Physical properties are observable/measurable without changing composition.
- Chemical properties involve reactivity and transformation into new substances.
- Always look for keywords: “changes into,” “reacts with,” “burns,” “rusts” → chemical. “Looks like,” “weighs,” “melts at,” “dissolves in” → physical.
