i believe you mean why does iron sink but the iron boat float. think about a balloon for a moment. if you take an empty balloon you can easily pull it under water, but if you fill the balloon with air and tie it shut, you cannot pull it under water. the same concept applies to the boat. The air inside and around the boat (yes, even if it is completely open with no roof) keeps it afloat

∙ 14y agoThe fact that a large steel ship will float is because of its shape. The ship displaces a huge volume of water equal to the volume of the submerged part of the hull. If the mass of the ship is less than the mass of the displaced water, the ship will not sink any lower so long as water is unable to enter the submerged portion of the hull. The mass of a pebble is more than the mass of the water it displaces, so the pebble sinks.

∙ 11y agoSteel is denser, thus heavier than water, so it sinks. However a ship can float because it displaces more water than it's own weight, replacing the weight of water with air inside the ship, which is lighter than the water it displaces. If the ship were filled with water or even steel it would sink. The spoon doesn't displace enough water to float.

∙ 10y agothe steel has a large amount of volume if air so it makes it lighter than the water displacement

Does a lump of iron float?
Solid iron will float in liquid Mercury. In most liquids it will sink.
Why does an iron ball sink and not an iron ship?
as relative density is directyy proportional to on surface area.... the iron ship being vast & having a huge surface area is able to float... whereas an iron ball being heavy & with less surface area sinks away..!
Why is a ship able to float on water?
A ship can float on water because of buoyancy. The shape of the ship and the displacement of the water it pushes aside when it enters the water create an upward force that counteracts the downward force of gravity. This buoyant force allows the ship to float and support its own weight.
Will a marker float or sink in water?
I have a marker which float in water.
Why does a piece of stone sink in water but a ship with a huge weight floats?
The ship is hollow. The stone isn't. The air trapped inside the ship allows it to float - despite it weight.
Does a lump of iron float?
Solid iron will float in liquid Mercury. In most liquids it will sink.
Will iron pyrite float?
No, a lump of iron pyrite will sink in water.
Will a lump of aluminum sink or float?
Sink
Does the element Iron float or sink in water?
yes iron does float in water yes iron does float in water
Does iron sulfide sink?
float
Can iron float in any liquid?
Solid iron will float in liquid mercury. In most liquids it will sink.

Do aluminum can peices sink or float?
Answer #1: float.==========================Answer #2:The density of aluminum is 2.7 gm/cm3.So, just like steel, if you shape a piece of it just right so that it displacesenough water, you can make it float. But a lump of it will sink in water.
How a nail sink in a water but the ships float?
Iron (or steel) has about 8 times the density of water. Therefore, the nail will sink. The ship also has empty spaces, with air, inside - thus the average density is less than that of water.
Why does a ship made of steel float when steel is dense enough to sink in water?
The ship has enough gas in it to keep it afloat.
Why does a ship made of iron floats while a piece of iron sinks?
Because the ship contains a large amount of air in it. But iron nail doesn't have any space to contain air in it. Air is a lightest thing. That can't sink in water. This method is used in submarines to sink it. There is a tank in the submarine. When they need to sink it they fill the tank with water. To float it they use to fill the tank with air.
As a ship travels from a river into the ocean it will be sink or float?
It will float - go a little higher, because of the higher density of salt water.
