According to Archimedes' Principle, an object placed in water will experience an upward force equal to
the weight of water the object displaces. It is this upward force that causes objects less dense than water
to float. For example, a cork floats when it is displacing a weight of water exactly equal to its own weight.
When placed in water, what percent of a cork's volume will remain above the surface? Complete the
explanation.
Density
g
Cork 0.24
cm
Water 1.00

cm3
A sample of cork with a volume of 1 cm3 has a mass of 0.24 g, so it floats when displacing water with a
weight of
g. This weight of water has a volume of cm', which is equal to the volume of
cork beneath the surface. Therefore, 1 cm - this volume =
% of the cork's volume,
will remain above the surface.
