Water Displacement Method

Front

What is the water displacement method?

Back

A technique used to measure the volume of an irregularly shaped object by observing how much water it displaces when submerged.

Front

How do you calculate volume displacement?

Back

Volume displacement is calculated by subtracting the initial water level from the new water level after an object is added.

Front

If the water level in a graduated cylinder rises from 30 ml to 45 ml after adding an object, what is the volume displacement?

Back

15 ml.

Front

What happens to the water level when an object is placed in it?

Back

The water level rises, and the amount it rises indicates the volume of the object.

Front

What is the initial water level in a graduated cylinder if the final level is 50 ml and the volume displacement is 10 ml?

Back

40 ml.

Front

Why is the water displacement method useful?

Back

It allows us to measure the volume of objects that do not have a regular shape.

Front

What unit is commonly used to measure volume in the water displacement method?

Back

Milliliters (ml).

Front

If a graduated cylinder shows a water level of 20 ml before adding an object and 25 ml after, what is the volume of the object?

Back

5 ml.

Front

What type of objects can be measured using the water displacement method?

Back

Irregularly shaped objects, such as rocks or toys.

Front

What is the volume of an object that displaces 12 ml of water?

Back

12 ml.
