Question

water displacement practice
directions: read the graduated cylinders to determine the starting volume and the volume after the object has been added. then subtract the initial volume from the total volume to calculate the volume of the object.
*reading at eye level from the bottom of the meniscus, the volume is 70 ml.
the volume of only water is: ______ ml.
the volume of water plus object is: ______ ml.
object volume = total volume - water volume
the volume of only the object is: ______ ml.
the volume of only water is: ______ ml.
the volume of water plus object is: ______ ml.
object volume = total volume - water volume
the volume of only the object is: ______ ml.

Explanation:

Step1: Determine water - only volume for first set

The water - only volume in the first graduated cylinder is 2 mL as the water level reaches the 2 - mL mark.

Step2: Determine water - plus - object volume for first set

The water - plus - object volume in the first graduated cylinder is 6 mL as the new water level reaches the 6 - mL mark.

Step3: Calculate object volume for first set

Using the formula $object\ volume=total\ volume - water\ volume$, we have $6 - 2=4$ mL.

Step4: Determine water - only volume for second set

The water - only volume in the second graduated cylinder is 30 mL as the water level reaches the 30 - mL mark.

Step5: Determine water - plus - object volume for second set

The water - plus - object volume in the second graduated cylinder is 50 mL as the new water level reaches the 50 - mL mark.

Step6: Calculate object volume for second set

Using the formula $object\ volume=total\ volume - water\ volume$, we have $50 - 30 = 20$ mL.

Answer:

First set:
The volume of ONLY WATER is 2 mL.
The volume of water PLUS object is 6 mL.
The volume of ONLY the object is 4 mL.
Second set:
The volume of ONLY WATER is 30 mL.
The volume of water PLUS object is 50 mL.
The volume of ONLY the object is 20 mL.
