It depends on the density of a substance, if it can float or not. If its mass per volume is less than the one of water, it floats. That means overall that the same volume of water would have a bigger weight than the one of the ship... and it floats... By the way: The volume of water the ship pushes away (under the water line) while floating, has just the weight of the ship. So if you're talking about a certain water deplacement of a ship, you're actually talking about the ship's weight ;-). Vic
boyancy in the hull of the ship
Metal ships are built to float.
A ship floats on the sea due to the principle of buoyancy. The weight of the water displaced by the ship is equal to the weight of the ship, allowing it to float. This is because the density of the ship is lower than the density of water.
A sea comprised of liquid, with the greatest possible density.
its anything that can float in sea like a submarine,ship, yacht etc
ship float in the sea because water has less density than any substance ship has much weight and thatswhy it sinks
"average density" You must combine the weight of the metal hull with that of the air contained within it.
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.
Mercury is a heavy metal, it will sink in sea water.
The water of the Dead Sea is unusually salty (even for a sea) and hence, it is also unusually dense.
It displaces water and is filled with air.
Displacement - the ship displaces an amount of water equal to its weight. Provided that this dowes not submerge the vessel, it will float.
