  • 2. 

    1 dm^3 measures

    • Length

    • Surface area

    • Volume

    • Density

    Correct Answer
    A. Volume
    Explanation
    The correct answer is volume because 1 dm^3 is a unit of measurement for volume. It represents the amount of space occupied by an object or substance.

    Rate this question:

  • 3. 

    Unlike mass or volume, the density of a substance is (                     ) of the size of the sample

    Correct Answer
    independent
    Explanation
    The density of a substance is independent of the size of the sample. This means that no matter how much or how little of the substance is present, its density will remain the same. Density is a physical property that is determined by the mass of the substance divided by its volume. Since both mass and volume are extensive properties that depend on the amount of substance present, the size of the sample does not affect the density.

    Rate this question:

  • 4. 

    Greek symbol used for density is

    • υ

    • π

    • ρ

    • θ

    Correct Answer
    A. ρ
    Explanation
    The Greek symbol used for density is ρ.

    Rate this question:

  • 5. 

    1 dm is equivalent to

    • 0.1 m

    • 0.1 cm

    • 0.1 km

    • 0.1 mm

    Correct Answer
    A. 0.1 m
    Explanation
    1 dm is equivalent to 0.1 m because the prefix "deci" means one-tenth. Therefore, 1 dm is equal to one-tenth of a meter, which is 0.1 m.

    Rate this question:

  • 6. 

    1 dm^3 is equivalent to

    • 0.001 cm^3

    • 0.001 m^3

    • 0.001 km^3

    • 0.001 mm^3

    Correct Answer
    A. 0.001 m^3
    Explanation
    1 dm^3 is equivalent to 0.001 m^3 because there are 10 decimeters in a meter. Therefore, if we have 1 cubic decimeter (dm^3), we can convert it to cubic meters (m^3) by dividing by 10. This gives us 0.1 m^3. Since the question asks for the equivalent in m^3, the correct answer is 0.001 m^3, which is the same as 1 dm^3.
