The air (within the ship) is less dense than water.,
a ship wreck is when a ship sinks and floats to the bottem of the ocean were it is filled with water and creatures of the sea.
It displaces water and is filled with air.
The iceburg made a hole in the sip and water started to leek in the ship then it got filled with water and it split in 2
A ship floats in sea water because it has a density less than that of the water it displaces. The shape of the ship also contributes to its buoyancy, as the hull design helps distribute the weight of the ship and enable it to displace enough water to stay afloat.
It makes the ships center of gravity sink lower in the water. This makes the ship more stable by making it less top heavy and by displacing more water. It gives it a larger base. Hooweestik.
The bulkhead is a wall running perpendicular to the length of the ship. Bulkheads divide a ship into sections along its length. The design of the bulkheads was a fatal flaw in the titanic because the bulkheads didn't go all the way up to the deck. Since the bulkheads only went part of the way up, the ship filled with water much like an ice-cube tray that's being filled with water. If the bulkheads had gone all the way up to the deck, only a portion of the ship would've filled with water and the ship wouldn't have sank.
A steel ship floats in water because of its shape and displacement. The design of the ship creates enough buoyant force to counteract its weight, allowing it to stay afloat. Additionally, the steel hull of the ship displaces enough water to keep it buoyant.
When vessel floats on a liquid, then it displaces a volume of that liquid, whose mass equals the mass of the vessel. If our vessel is hollow, as a ship or a bowl would be, then there is available some of the volume for the carrying of a load. Archimedes is attributed with this discovery.
When a subs surfaced, it's a regular ship. It displaces water (it's filled with air NOT WATER).
The very basic answer is, it struck and iceberg which created a gash in the side of the ship an it filled with water.
A ship will float on the water if it has less density than the water. That includes any air trapped inside the ship - so to calculate the density, you divide the total mass by the total volume. More generally, any object will float on any liquid (or in any gas, for that matter) if it is less dense than the liquid or gas.
A large ship can float in water due to the principle of buoyancy. The weight of the water displaced by the ship is equal to the weight of the ship itself, allowing it to stay afloat. The shape of the ship's hull and the distribution of weight also play a role in helping it float.
