Ignoring shapes (using cubes), density (mass/volume) greater than "water" means it sinks. The floating object displaces its weight of the buoyant "object" (water, etc.)when it floats, but displaces its volume when it sinks.
That works for air, too. If the average density of a balloon is less than the density of the air, it floats.
Lower density=higher bouyancy
Due to hydrogen bonds, the density of water decreases as it freezes (decrease starts at 4oC). To see a full explanation of why ice floats in water, see the related question below.
If a object has buoyancy it floats. A object also needs to have a density less dense than the object you want it to float on. Example: if you want a inner tube to float and jewelry to sink you make them out of different materials.
Percentage salt content effects density and thus buoyancy
by wars and things like that
Density and the composition of the different layers affect the behavior of seismic waves.
If it alters its density, yes.
density
If the average density of an object is less than water (1.0 g per mL) it will float in water, and if it is more than 1.0g/mL it will sink in water. So the lower the density, the greater the buoyancy.
greater density tends to less buoyancy
If the mass stays the same, then when an object gets larger, its density decreases. The larger density=the more bouyancy
The higher the density the lower the buoyancy.
A body has positive buoyancy when its density is lower than the density of the fluid the body is in.
buoyancy has to deal with density, gravity, air, and water
Buoyancy
Yea
yes it does when they touch the particle dies(atomns)
Buoyancy is the ability to float, so if the density is high, it'll hold up something. (see? FLOATING. BUOYANCY.)
