Questions and Answers
  • 1. 

    Three objects are cut from the same sheet of steel. They are different shapes but they all have the same mass.                   disc                                          square                                   L-shape Which object has the greatest density?

    • A.

      All have the same density

    • B.

      The disc

    • C.

      The square

    • D.

      The L-shape

    • E.

      None of the above is the answer

    Correct Answer
    A. All have the same density
    Explanation
    The given question states that three objects, a disc, a square, and an L-shape, are cut from the same sheet of steel and have the same mass. The question asks which object has the greatest density. The correct answer is that all the objects have the same density. Density is defined as mass divided by volume, and since all three objects have the same mass, their densities will also be the same. Therefore, none of the objects has a greater density than the others.

    The mass of a paper clip is 0.50grams and the density of its material is 8.0g/cm3. The total volume of the number of clips is 20cm3. How many paper clips are there

    • A.

      320

    • B.

      160

    • C.

      240

    • D.

      80

    • E.

      10

    Correct Answer
    A. 320
    Explanation
    The density of a material is defined as its mass divided by its volume. In this case, the mass of one paper clip is given as 0.50 grams and the density of the material is given as 8.0 g/cm3. To find the volume of one paper clip, we can rearrange the density formula to solve for volume: volume = mass/density. Plugging in the values, we get volume = 0.50 g / 8.0 g/cm3 = 0.0625 cm3. The total volume of the number of clips is given as 20 cm3. To find the number of paper clips, we can divide the total volume by the volume of one paper clip: 20 cm3 / 0.0625 cm3 = 320 paper clips. Therefore, the correct answer is 320.

    The level of water in a measuring cylinder is 75cm3. A stone of volume 20cm3 is lowered into the water. What is the new reading of the water level?

    • A.

      95cm3

    • B.

      55cm3

    • C.

      75cm3

    • D.

      20cm3

    Correct Answer
    A. 95cm3
    Explanation
    When the stone with a volume of 20cm3 is lowered into the water, it displaces an equal volume of water. This means that the water level will rise by 20cm3. Therefore, the new reading of the water level will be the initial reading of 75cm3 plus the volume of the stone, which is 20cm3. Hence, the new reading will be 95cm3.

    If a block of copper measures 2.00cm  x  4.00cm  x  5.00cm and weighs 356grams. What is it density?

    • A.

      8.9g/cm

    • B.

      8.9kg/m3

    • C.

      8900kg/m3

    • D.

      8900g/cm

    • E.

      None of the above is the answer

    Correct Answer
    C. 8900kg/m3
    Explanation
    The density of a substance is defined as its mass per unit volume. In this question, the mass of the copper block is given as 356 grams, and its dimensions are given as 2.00cm x 4.00cm x 5.00cm. To calculate the density, we need to convert the mass to kilograms and the volume to cubic meters. The mass of the copper block is 0.356 kg (since 1 kg = 1000 g), and the volume is (2.00cm x 4.00cm x 5.00cm) = 40 cm³ = 0.00004 m³ (since 1 m³ = 1,000,000 cm³). Dividing the mass by the volume, we get a density of 0.356 kg / 0.00004 m³ = 8900 kg/m³. Therefore, the correct answer is 8900kg/m3.

    Bonus Questions! A box has an internal volume of 1000cm3. When a solid object is placed in a closed box, the volume of air in the box is 520cm3. The density of the object is 8.00g/cm3. What is the mass of the object? The mass of the object is ________________grams. (Enter your answer in the box)

    Correct Answer
    3840, 3,840, 3 840
    Explanation
    The mass of an object can be calculated by multiplying its volume with its density. In this case, the volume of the object is the difference between the internal volume of the box and the volume of air in the box, which is 1000cm3 - 520cm3 = 480cm3. The density of the object is given as 8.00g/cm3. Therefore, the mass of the object can be calculated as 480cm3 * 8.00g/cm3 = 3840g.
