Is is related through Archimedes principle, which states that the buoyancy force on an object is equal to the weight of liquid displaced by the submerged object. The weight of a volume of water is equal to the volume x density of water x the gravitational constant.FB = V ρ g
Many densities can occur. Mercury has a much higher density than water, for instance. Just as aside, water is not uniformly dense. It is less dense at 32 degrees F than at 39 degrees F. So even within a specific liquid the density can change.
Whether a material in any state of matter (solid, liquid or gas) will float in a liquid (or a gas) depends on the relative densities of the materials. (Density is defined as mass divided by volume.) If the density of the object is less than the density of the liquid it is placed in, the object will float. If the density of the object is greater than the density of the liquid, the object will sink. If the densities are the same, the object will remain stationary assuming there are no other forces acting on it. For a few examples, a plank of wood is (generally) less dense than water, so it would float. A balloon filled with Helium is less dense than air, so it rises. A ball of lead is more dense than water, so it sinks. You can even float a liquid on top of another liquid if their densities are different.
You must compare the densities of the object and whatever substance you are putting it in. If the density of an object is greater than the substance it is in, then the object will not float on the surface Tomatoes are denser than water
They all have densities greater than the density of the fluid in which they are sinking. The mass of the displaced liquid is less than the mass of the sinking body.
Ice is less dense than liquid water.
Ice is less dense than liquid water.

The densities are equivalent.
their density is less than that of water
Basicly, liquid water is more dense then frozen water. That's why ice floats on water!
Water density depends on the temperature. See this table for density.

They have different densities. If one liquid ( say water) is mixed with another that is lighter in density ( say oil) the lighter density will float on top. Try it!

Water has a lower density as a solid than it does as a liquid. In the vast majority of substances are denser as solids than as liquids.
This is the determination of the specific density (the ratio liquid density/water density).
