The density of the fluid versus the density of the object....


If #rho_"object">rho_"fluid"# the object SINKS...

If #rho_"fluid">rho_"object"# the object FLOATS..

The human body is more or less composed of water. And we more or less can float on fresh water. Why should we be more buoyant in the ocean than in fresh water?
