Moore 1.3 The International System of Units (SI)

1. Which of the following is the unit for density?

G/cm^3

Kg

ML/kg

M/s

The unit for density is g/cm^3 because density is defined as mass per unit volume. In this unit, grams (g) represent the mass and cubic centimeters (cm^3) represent the volume. This unit is commonly used for measuring the density of solids and liquids.

Explanation

The unit for density is g/cm^3 because density is defined as mass per unit volume. In this unit, grams (g) represent the mass and cubic centimeters (cm^3) represent the volume. This unit is commonly used for measuring the density of solids and liquids.

2. 1 dm^3 measures

Length

Surface area

Volume

Density

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.

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.

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

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.

4. Greek symbol used for density is

υ

π

ρ

θ

The Greek symbol used for density is ρ.

Explanation

The Greek symbol used for density is ρ.

5. 1 dm is equivalent to

0.1 m

0.1 cm

0.1 km

0.1 mm

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.

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.

6. 1 dm^3 is equivalent to

0.001 cm^3

0.001 m^3

0.001 km^3

0.001 mm^3

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.

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.
