Answer: Transparency (transparent, translucent, or opaque). Glass is transparent; wax paper is translucent.

Flashcard 22: What physical property describes how easily a material can be hammered into a thin sheet?

Answer: Malleability. Gold and aluminum are malleable; ceramics are not.

Flashcard 23: Which physical property describes whether a material is attracted to a magnet?

Answer: Magnetism. Iron and nickel are magnetic; aluminum is not.

Flashcard 24: What physical property describes how hard it is to scratch a material?

Answer: Hardness. Resistance to being scratched or dented.

Flashcard 25: What is the formula for density using mass $m$ and volume $V$?

Answer: $D=\frac{m}{V}$. Divide mass by volume to find density.

Flashcard 26: What physical property describes how rough or smooth a surface feels?

Answer: Texture. Detected by touch, ranging from bumpy to silky.

Flashcard 27: What is a physical property of a material?

Answer: A characteristic observed without changing the material's identity. Can be observed without creating a new substance.

Flashcard 28: Which physical property describes how hard it is to scratch a material?

Answer: Hardness. Diamond is very hard; chalk is soft.

Flashcard 29: Which option correctly states the formula for density?

Answer: $D=\frac{m}{V}$. Density equals mass divided by volume.

Flashcard 30: What physical property describes how shiny a material is?

Answer: Luster. Metals typically have high luster.

Flashcard 31: What physical property describes whether a material can be hammered into a thin sheet?

Answer: Malleability. Metals like gold and aluminum show this property.

Flashcard 32: Identify the state of matter for a material that has a fixed volume but no fixed shape.

Answer: Liquid. Takes the shape of its container but doesn't expand.

Flashcard 33: What term describes a material that does not let light pass through?

Answer: Opaque. Blocks all light like wood or metal.

Flashcard 34: Which physical property describes the ability to be pulled into a wire?

Answer: Ductility. Copper can be stretched into electrical wires.

Flashcard 35: What term describes a material that lets some light through but not clearly?

Answer: Translucent. Like frosted glass that blurs what's behind it.

Flashcard 36: Which physical property describes how well a material allows heat to pass through it?

Answer: Thermal conductivity. Metals conduct heat well; plastics are insulators.

Flashcard 37: What is density?

Answer: Mass per unit volume. How tightly packed matter is in a given space.

Flashcard 38: Calculate density for $m=30\text{ g}$ and $V=10\text{ mL}$ using $D=\frac{m}{V}$.

Answer: $3\text{ g/mL}$. $D = \frac{30}{10} = 3$ g/mL.

Flashcard 39: Identify the density when mass is $12\,g$ and volume is $3\,mL$.

Answer: $4\,\frac{g}{mL}$. Apply $D=\frac{m}{V}$: $\frac{12\,g}{3\,mL}=4\,\frac{g}{mL}$.

Flashcard 40: Which word describes a material that does not let light pass through?

Answer: Opaque. Blocks all light, like wood or metal.

Flashcard 41: Which word describes a material that lets most light pass through clearly?

Answer: Transparent. Like clear glass or clean water.

Flashcard 42: What is density?

Answer: Mass per unit volume. Tells how tightly packed the matter is.

Answer: Graduated cylinder. Narrow shape and markings ensure accurate readings.

Flashcard 44: Identify the state of matter for a material that has no fixed shape and no fixed volume.

Answer: Gas. Particles spread out to fill any container completely.

Flashcard 45: Identify the physical property that describes resistance to scratching (for example, a nail test).

Answer: Hardness. Harder materials scratch softer ones.

Flashcard 46: What is the difference between a physical property and a chemical property?

Answer: Physical: no new substance; chemical: forms new substances. Physical changes are reversible; chemical changes create different materials.

Answer: Ductility. Metals like copper are ductile; glass is not.

Flashcard 48: Which formula shows density in terms of mass and volume?

Answer: $density = \frac{mass}{volume}$. Divide mass by volume to find how dense something is.

Answer: A characteristic describing how a substance can change into new substances. Involves transformation into different substances.

Flashcard 50: What physical property describes whether light passes through a material?

Answer: Transparency (transparent, translucent, or opaque). Materials interact with light in these three distinct ways.

Flashcard 51: Which term best describes a material that lets some light through but blurs images?

Answer: Translucent. Like frosted glass or thin paper.
