Steel ships float? Why does the iron ship float water despite the fact that steel has a density greater than water. Because steel has a density greater than water, thus drowning. If steel and make a light-year interpretation is the shape of a boat. The volume is increased, in spite of the same mass. The steel has a density less than water so it floats in water. Of an object can float in any liquid. Because the object is less dense then liquid, such as a piece of wood has a density of 0.9 G/cm3, floating in the water, which can have a density of 1 G/cm3. That object can float in water because the object has a density less than water, and water pressure, floating objects. This force is called the "buoyancy buoyancy, or force." This force, which will depend on the amount of water that is the object. The closer an object is exposed to much space or replace the water as much. So if the radiating object with curved edges up similar ships. The object then it will float.
