Question

Explain how a ship made of materials that are much denser than water is able to float on water?

Answer 1

hmm let me think

Answer 2

k

Answer 3

ohhh wait i think i got it

Answer 4

I think it is: Imagine how a ship is when it hits the water. All ships are made of stuff much denser than water. Why is this? I think like when you fill a sink with water then try to put a cup in that sink where the open part is faced up it will not go in. So if you aply this to a ship they have a open part faced up to have air in here which makes the ship float. I may have not been totally acurate.

Answer 5

Hmm... @UltimateWitherLord Good try !

Well, Consider an object in the fluid experiences an upward force equal to the weight of the fluid displaced by the object. So for an example, if a ship weighs 1,000 pounds (or kilograms), it will sink into the water until it has displaced 1,000 pounds (or kilograms) of water. Provided that the ship displaces 1,000 pounds of water before the whole thing is submerged, the ship floats.

It is not very hard to shape a ship in such a way that the weight of the ship has been displaced before the ship is completely underwater. The reason it is so easy is that a good portion of the interior of any ship is air (unlike a cube of steel, which is solid steel throughout). The average density of a ship-- the combination of the steel and the air -- is very light compared to the average density of water. So very little of the ship actually has to submerge into the water before it has displaced the weight of the ship.

@magy Does this explains well ?
