Buoyancy
Difference in density.
Density!!
Color
To predict whether an object will sink or float in a liquid, you must first examine the densities of both the object and the liquid. If the object is more dense than the liquid, it will sink. If the object is less dense than the liquid, it will float. For example, the density of water is approximately 1g/ cm3. The density of ice is approximately 0.92 g/ cm3. That is why when water freezes, the ice floats on the top rather than sinking to the bottom.
i think you mean how does an object float if you did here is the answer most solids float on liquid because it has air in it (sponge) or it is lighter than the liquid.
Well usually, the bigger the volume, the better it floats. But mostly, it matters about how much mass an object contains.
Density!!
Push it down, and measure the displaced liquid.
If you push it down, you can measure the volume of the displaced liquid.
An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
You can push it under water / under the liquid's surface, and measure the displacement of liquid.
it means the liquid is heavier. It floats in the liquid.
It is impossible to tell; whether an object floats or sinks depends on its density, not on its weight.
In general, whether an object sinks or floats doesn't depend on its size, but rather on its density. If it is denser than the liquid in which it is placed, it will sink; otherwise it will float.

An object floats when the objects density is LESS than the liquid your using.
Archimedes discovered that when an object floats in a liquid, it will displace a volume of that liquid which is equal in weight to the object.
