It depends on the buoyancy of an object in relation to the liquid it is in.
it will float
objects float better because chemicals help make the objects float higher. the more salt the higher the things go
You can't make a bar of metal float on water, but boats with metal hulls float. Also, metal bars and other metal objects float on mercury.
Because it is more dense
objects that are less dense float to the top.
A submarine
Objects that are less dense than the environment in which they are immersed will float, unless they are tethered.
An object can float on water only if its density is less than water.(Archimedes principle). So, to make an object float, its density should be low. For this purpose, its mass should be less and volume should be greater(d=m/v), so to make heavy objects to float, their volume should be as less as possible.

Objects that float in water have a lower density than water. -anonymous18_K
Objects that are less dense than the environment in which they are immersed will float, unless they are tethered.
Because some objects are a lot denser than water so the sink and others are less denser so they float
