@it's called buoyancy because some things are heavier than others .......................... that is a good theory but no, buoyancy does cause it but buoyancy also needs air pressure took keep afloat .
the density of each of the fats. the higher density, the lower it will be in a mixture
because of buoyancy!
no it causes it to fall
Because of density difference. High density causes the body to sink and low density makes the things to float on the surface.
things that are more dense sink while things that are less dense float
Substances with a density (mass per unit volume) greaterthan a liquid will sink in the liquid; if the object has a lower density it will float.
Maybe because they build it to not sink and some things sink because it is how it's made
All oceanic plates float on top of the mantle, and sink into the mantle underneath a less dense plate in plate collision zones.
It is quite common for various things to float in water. But any liquid can cause things to float.
things float in air because of density
No, it rises because of buoyancy. For a really good non-mathematical explanation go to the answer in the Related Answers section below called Why do some things float but not others.
You can't make things float, things float by it's self's it's density is lower than 1 it can float, if it's density is greater than 1 it can't float.
