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.
What is the volume of a piece of metal?
The Volume of steel used should always be less than the volume of ship made out of it.The ratio could differ and hence there may be no specific ratio.The greater the (Ratio of Volume of ship:Ratio of Volume of steel used) say 3:1that means the ship can carry about 2 times the volume of the steel used.That means the water displaced would be 3 times volume of steel hence the water is applying the force on ship is 3 times weight of steel.***STUDY BUOYANCY
If something floats in water does the water have more or less density?
The general rule is that an object will float, if it has less density that the liquid (or gas) in which it is placed. If the density of a liquid is greater, a larger amount of objects will float. Also, the same object will float higher, if it is placed in a denser liquid.
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.
Which floats better low density or high density substances?
Because if you look at the volume it occupies the ship will still weigh less than the same volume of water. The Greek scholar Archimedes realised when he was taking a bath what is now called his 'Law'. It is said that he ran into the street naked shouting "Eureka!" (I've found it!), although this is a legend. In his bath he realised that when an object is placed in water it experiences a force upwards (an 'upthrust') equal to the weight of water it displaces. If the upthrust is more than the weight of the object pulling downwards, the object floats. If the upwards force is too small to counteract the downwards weight of the object, it will sink. Because of its shape, even though a ship is made from dense materials, it still displaces enough water to create an upthrust larger than the weight of the ship, so it floats. However, if you somehow crushed the ship into a block, although it would weigh exactly the same, because it displaced less water, it would sink.
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.
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.
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.
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.
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.
How does the ship of a steel ship allow the ship to float?
small water displacment compared to ships size
A steel needle sinks in h20 but a steel ship floats?
The needle is solid, it's density higher than water's. The ship is hollow, its overall density lower than water's.
What are 2 reason a steel ship floats in water?
1. The hull of the ship is filled with air, not water. 2. The ship is heavy so is partially submerged.
How can a ship made out of steel with a density much higher than the density of water float on the water?
The steel has a density greater than water; but the ship does not. To calculate density, you divide mass by volume. This includes the mass - and the volume - of any air trapped inside the ship.
How does the shape of a steel ship allowed to ship to float?
small water displacment compared to ships size
