It depends on what you want to float it on.
For instance if you want to float a ball in oil the ball's density must be less than the oil's density.
when a object float it has density
The Density.
-- If the object floats in water, then its density is less than the density of water. -- If the object sinks in water, then its density is more than the density of water. -- If the object floats in air, then its density is less than the density of air. -- If the object sinks in air, then its density is less than the density of air.
it is not a part it is the bouancy of the material
the amount of density
It is impossible to tell; whether an object floats or sinks depends on its density, not on its weight.
If an object floats on water, it means its density is less than that of water. You can calculate the density of the object by comparing its weight to its volume, using the formula density = mass/volume. The density of water is about 1 g/cm^3, so if the object floats on water, its density will be less than 1 g/cm^3.
We both know it floats
The color or surface texture of an object will never affect whether it sinks or floats. The buoyancy of an object is dependent on its density compared to the density of the fluid it is placed in.
If the object's density is greater than the density of the fluid you put it in, then it sinks. If less, then it floats in that fluid.
An object floats when the objects density is LESS than the liquid your using.
