Volume by Water Displacement
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Volume of an irregular object equals the rise in a liquid's level once it is fully submerged, since it displaces its own volume.
Show
Lowering a stone into a cylinder reading 25.0 mL raises it to 32.0 mL, so the stone's volume is 7.0 mL.
Watch for
The object must stay fully submerged and must not dissolve or trap air, or the reading is unreliable.
