Question

In the water displacement method for finding volume:

A. You subtract the final volume from the initial volume

B. You subtract the initial volume from the final volume

C. You add the initial and final volumes

D. You divide the final volume by 2

Answer 1

The correct answer to the question is B. You subtract the initial volume from the final volume. In the water displacement method, the volume of an object is calculated by subtracting the initial volume of water from the final volume after the object is submerged, which gives the volume of the water displaced.

Step-by-step explanation:

To determine the volume of an object using the water displacement method, you would measure the volume of water before and after the object has been submerged. The difference in volume gives the volume of the object.

The correct answer to the question is B. You subtract the initial volume from the final volume.

This means that if the initial volume of water in a graduated cylinder is 50 mL, and after placing the object in the cylinder the volume rises to 70 mL, the volume of the object is calculated as:

• Vobject = Vfinal - Vinitial
• Vobject = 70 mL - 50 mL
• Vobject = 20 mL

This volume of the object is equal to the volume of water displaced by the object.
