A solid steel block sinks in water because its density is greater than that of water. However, a steel ship is designed with a shape that allows it to displace enough water to create a buoyant force greater than its weight, allowing it to float. The overall density of the ship is less than that of water, allowing it to stay afloat.

What is formula for block coefficient?
The block coefficient (CB) is calculated as the ratio of the underwater volume of a ship's hull to the volume of a rectangular block that has the same overall length, breadth, and draft as the ship. The formula for block coefficient is: [ CB = \frac{V_{ship}}{L \times B \times T} ] Where: CB = Block coefficient Vship = Underwater volume of the ship's hull L = Length of the ship B = Breadth of the ship T = Draft of the ship
How can a massive steel ship float on water?
A ship floats on water due to the principle of buoyancy, which is determined by its weight and the weight of the water it displaces. The shape of the ship's hull helps distribute its weight evenly and creates upward pressure, allowing it to stay afloat. The buoyant force acting upward on the ship counteracts the force of gravity pulling it down, keeping it on the surface of the water.
How is the density of a steel ball different from a steel ship?
Density = mass/volume let us say the mass of the steel ball and the ship are same. but the steel ball is fully enclosed, a tight spherical volume, where as the ship is a hollow, occupies more volume (multiple times) as that of the spherical ball. Considering the first equation, u know well the density of steel ball is much higher than the steel ship.
Why Battleships floats and does not sink?
Battleships are designed with a hull that displaces enough water to keep them afloat. The hull is usually made of materials that are less dense than water, such as steel or aluminum, allowing the ship to remain buoyant. Additionally, the ship's compartments are sealed to prevent water from flooding in.
A ship catches fire and its steel hull expands as it heats up what happens to the volume of water the ship displaces?
Odd but good question.It's instructive to know a little about buoyancy. A floating object will always displace its own weight in water.If I have an icecube that weights 10g and put it into some water, it will be semi-submersed. The volume of water it displaces is equal to the volume of the icecube that is under water. That volume, if it were water, would weigh the same as the ice cube.So our ship has displaced it's own weight in water. When the ship is on fire, its weight does not change and so the displaced water weighs the same, hense its volume is also the same. Simple as that.This is of course ignoring several very minor effects:If fumes escape the burning ship, its weight will change slightly.Our archimedes-style analysis also does not account for surface tension (which will change as water heats up around the burning boat and also as the hull expands) but I guarentee you this effect is too small to matter or perhaps even measure.
If the density of a solid is greater than that of water it sinks why then does a steel ship float in water when the density of steel is about eight times that of water?
The density of the entire ship is much less than the density of a ship-sized block of steel. That's accomplished by flattening the block of steel into a giant sheet, and then rounding the sheet on the bottom, so that it displaces much more water than the original solid block would. The final structure still has the same mass as the block of steel, but it has much more volume ... the volume of the steel, plus the additional volume of the cargo holds, the engine room, the galleys, the passenger cabins, the radio room, etc. So the original mass divided by the much greater volume winds up being a much smaller density than steel has. In fact, it winds up being smaller than the density of water.
How ship floats on water surface?
The density of the VOLUME of the ship is less than the density of the water it displaces (pushes out of the way). While the steel of a steel hulled ship is denser than water, the steel plus the air enclosed by the steel is less dense.
Why does a cruise ship float but a block of steel will sink?
According to Archimedes' principle, a body in fluid, wholly or partly submerged, experiences an upward force (buoyancy) which is equivalent to the weight of the fluid displaced. The ship has a shape which displaces more water than a block of steel and so experiences a greater upward force.
How can a ship float on the ocean if it ways like a ton or more?
The shape of the ship allows it to float. Imagine a ship that was just a big block of steel, If you put that steel block into water, it would sink because it is denser than water. Ships are built with a hollow shape. The amount of steel is the same, but the hollow shape decreases the boat's density. Water is denser than the hollow boat, so the boat floats. Shaping the block into a hollow form increases the volume occupied by the same mass, which results in a reduced overall density. The ship floats because it is less dense than water.
Why do steel ships float on water if steel is denser than water?
Steel ships float on water because of the principle of buoyancy. The weight of the water displaced by the ship is equal to the weight of the ship itself, causing the ship to float. The shape of the ship also plays a role in its ability to displace water and stay afloat.
Why will a ship of steel sink while a ship of air wont?
It's possible that a ship of steel will not sink as well. But if it will sink, it would be because the density of steel is greater then the density of water, while air's density is lower then water's.
Can you float a block of steel in water?
Not as long as it's still in the shape of a block. But if you re-shape it into the shape of a cup ... whether round or rectangular ... it will float, because it displaces much more water than a block does. If your cup-shape is done artistically and with care, people may call it what it looks like ... a little "boat" or "ship". Those objects are usually made out of re-shaped blocks of steel.
What are 2 reason a steel ship floats in water?
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.
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 steel ship float?
A steel ship floats because of 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.
How does the ship of a steel ship allow the ship to float?
small water displacment compared to ships size
How does a steel ship float in water?
A steel ship floats in water because of a principle called 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 also helps distribute the weight evenly, helping it to float.
