# Worksheet: Measuring Volumes

In this worksheet, we will practice identifying correct and incorrect uses of measuring cylinders for measuring the volumes of liquids and gases.

Q1:

The diagram shows a measuring cylinder with a liquid in it. What is the volume of the liquid? Q2:

The diagram shows a measuring cylinder with a liquid in it. What is the volume of the liquid? Q3:

Which of the following instruments is used to measure the volume of a liquid?

• AA weighing scale
• BA meter ruler
• CA multimeter
• DA measuring cylinder
• EA thermometer

Q4:

Elizabeth uses a measuring cylinder to find the volume of a liquid. What value does she find? Q5:

Victoria uses two measuring cylinders to find the volume of a liquid. She fills the first cylinder up to the top and then pours the rest of the liquid into the second cylinder, as shown in the diagram. She determines that the total volume of the liquid is 90 mL. Which of the following statements explains why this answer is incorrect? • AVictoria is reading from the top of the meniscus of the liquid in the first cylinder, rather than the bottom.
• BVictoria is reading from the bottom of the meniscus of the liquid in the first cylinder, rather than the top.
• CVictoria has not accounted for the liquid above the 50 mL mark on the first cylinder. The actual volume of the liquid is greater than 90 mL.

Q6:

Scarlett uses two measuring cylinders to find the volume of a liquid, as shown in the diagram. She determines that the total volume of the liquid is 75 mL. Which of the following statements explains why this answer is incorrect? • AThe resolutions of the two cylinders are not the same; therefore, they cannot be used together.
• BScarlett is reading from the bottom of the meniscus of the liquid, rather than the top.
• CScarlett is reading from the top of the meniscus of the liquid, rather than the bottom.
• DThe scales of the two cylinders have different units. There is 25 cL  of liquid in the left-hand cylinder, which is equal to 250 mL.

Q7:

Jennifer uses a measuring cylinder to find the volume of a liquid that she pours from a jug, as shown in the diagram. She determines that the volume of the liquid in the cylinder is 38 mL. Which of the following statements explains why this answer is incorrect? • AJennifer is reading from the top of the meniscus of the liquid, rather than the bottom.
• BEach minor dash on the scale corresponds to 1 mL; thus, the volume is actually 41 mL.
• CThe resolution of the measuring cylinder is 5 mL; thus, the answer should be rounded up to 40 mL.
• DThe measuring cylinder is tilted at an angle, and the liquid within it is higher on one side of the scale than the other. This means that the reading is higher than it should be.
• EJennifer is reading from the bottom of the meniscus of the liquid, rather than the top.

Q8:

Archimedes wanted to measure the volume of a gold crown. He placed it in a measuring cylinder that was partially filled with a liquid so that the crown was fully submerged, as shown in the diagram. What was the volume of the crown? Q9:

Benjamin tries to measure the volume of some plastic cubes using a measuring cylinder. He puts the plastic cubes in the cylinder, as shown in the diagram, and he determines that the volume of the cubes is 26.5 mL. Which of the following statements explains why this answer is incorrect? • AThe height in the cylinder that the cubes reach is not even. Therefore, he should take an average of where the top of the cubes reaches.
• BThere are gaps between the cubes, which take up some of the volume in the cylinder below the 26.5 mL line. Thus, the actual volume of the cubes is less than 26.5 mL.
• CHe was reading from the top of where the cubes reach, rather than the bottom. The correct answer should be read from the bottom of where the cubes reach, which is 23.5 mL.
• DEach minor tick mark on the scale corresponds to 1 mL; therefore, the actual answer is 28 mL.

Q10:

The diagram shows a pipette containing a volume of liquid. Each interval between the markers of the pipette represents 1 mL of liquid. What is the volume of the liquid in the pipette? Q11:

Daniel uses a pipette to transfer a small amount of liquid from one container to another. As he does so, he holds the pipette up to measure how much liquid is in it, as shown in the diagram. Each interval between the markers of the pipette represents 1 mL of liquid. He determines that the volume of the liquid in the pipette is 2 mL. Which of the following statements explains why this answer is incorrect? • ADaniel is reading from the wrong end of the scale. The actual volume is 5 mL.
• BThe pipette must be held the other way up in order to use the scale on it to measure the volume of liquid inside.
• CDaniel is reading from the bottom of the meniscus of the liquid in the pipette, whereas he should be reading from the top.
• DDaniel is reading from the top of the meniscus of the liquid in the pipette, whereas he should be reading from the bottom.
