Buoyancy depends on volume and so an object's buoyancy reduces if it is compressed and increases if it expands. The buoyancy also changes if the density of the external fluid changes.

Buoyancy describes the tendency of an object to float or rise in a fluid when submerged; this fluid can be either a liquid or a gas.
