The structure of an iron ship is such that its density is less than that of water. Anything with a density less than water will float in water.
if u made the piece ofmetal hollow it can float unless its density is larger than the water densityANSWER:If you make it displace more water than what makes it sink, it will float, as in a ships hull. If you make pontoons out of it, it will float. If you make an enclosed shape that contains enough air, it will float. There should be less density in the item than the water.
If it is more dense than water, like gold or iron or mercury or granite, it will sink. If it is less dense than water, like styrofoam, oil or coconuts, it will float. The density of water is very very close to 1 gram per millilitre, or 1 kilogram per litre. Out of interest, ships float becasue they have a lower density than water. Although they are iron, the air within the ships hull makes them less dense than water.
It depends. A steel ship will float just fine, so will an iron one(i.e. Old Ironsides). It all depends on the size, weight, and buoyancy of the ship.
Iron is almost 8 times heavier than water so it is not buoyant at all. Ships float because they are just a shell and can displace a large amount of water.
Solid iron will float in liquid mercury. In most liquids it will sink.
Iron sinks in water because it is denser than water. The density of iron is about 7.87 g/cm^3, while the density of water is 1 g/cm^3. This difference in density causes iron to sink when placed in water.
Because the boat has a special shape that makes it less dense than water.
Iron will float in oil in most cases. However, for iron to float in oil, it must have a density which is lower than the oil.
Cruise ships float with help from density and a principal called buoyancy.because of greater surface area.
The ships are built in drydocks which can be flooded to float the ships out.
The ships are not made of solid iron. They contain much empty space where the cargo and or passengers go. So the overall density of a ship: its TOTAL mass divided by its TOTAL volume is less than that of water.
Marbles float due to their low density relative to water, while ships float because of their shape and the principle of buoyancy. The shape of ships allows them to displace a large volume of water, which creates an upward buoyant force that supports their weight.
