    Flexibility. Flexible materials bend; brittle ones break.

18. Identify the volume when mass is $20\,g$ and density is $5\,\frac{g}{mL}$.

    $4\,mL$. Rearrange to $V=\frac{m}{D}$: $\frac{20\,g}{5\,\frac{g}{mL}}=4\,mL$.

19. What physical property describes whether a material is attracted to a magnet?

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

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

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

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

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

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

    Hardness. Resistance to being scratched or dented.

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

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

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

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

27. What is a physical property of a material?

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

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

    Hardness. Diamond is very hard; chalk is soft.

29. Which option correctly states the formula for density?

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

30. What physical property describes how shiny a material is?

    Luster. Metals typically have high luster.

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

    Malleability. Metals like gold and aluminum show this property.

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

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

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

    Opaque. Blocks all light like wood or metal.

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

    Ductility. Copper can be stretched into electrical wires.

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

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

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

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

37. What is density?

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

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

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

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

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

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

    Opaque. Blocks all light, like wood or metal.

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

    Transparent. Like clear glass or clean water.

42. What is density?

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

43. Which tool is best for measuring the volume of a liquid sample?

    Graduated cylinder. Narrow shape and markings ensure accurate readings.

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

    Gas. Particles spread out to fill any container completely.

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

    Hardness. Harder materials scratch softer ones.

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

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

47. What physical property describes how easily a material can be pulled into a wire?

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

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

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

49. Which option best defines a chemical property?

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

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

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

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

    Translucent. Like frosted glass or thin paper.

52. What physical property describes the amount of matter in an object?

    Mass. Measured in grams or kilograms.

53. Identify the state of matter for a material that keeps its own shape and volume.

    Solid. Particles are tightly packed and vibrate in place.

54. Which physical property describes a material that breaks or shatters easily?

    Brittleness. Glass and ceramics are brittle materials.

55. What physical property describes a material's ability to bend without breaking?

    Flexibility. Rubber bands and plastic rulers show this property.
