A ship will sink more easily, when in fresh water instead of sea water, as the fresh water is less dense, due to a lack of salt in it. The density of any object affects how well it's able to float.

∙ 11y agoThe change is subtle between sea water and freshwater, but the reason the boat floats better in sea water is because there is salt in the water making the water more dense. This aids in the flotation of a boat. In freshwater, there is no salt so the density of the water is less dense

Why do needle sinks in water but ship floats?
Whether something sinks when it's placed on water is determined by the amount (weight) of water that it displaces. The needle, being small in size and relatively high in mass (relative to its size), displaces very little water when it is placed on the surface. The weight of the needle will be more than the weight of the water that it displaces and the needle will sink. The ship, though many times heavier than the needle, will displace alot more water than the needle. The ship will float if the weight of the displaced water is more than the weight of the ship.
Why is it that ship floats deeper in fresh water than in the sea water?
sea water is denser.
What is reason that a steel ship floats while a steel needle sinks?
The displaces a sufficient amount of water to keep it afloat
Does the ship sink or rise in salt water?
The ship has two forces that affect the fraction of its volume that is above the surface of the water. The ship's weight is the downward force. The buoyant force is the upward force. Since the ship is floating, the magnitudes of these two forces are equal. The buoyant force is dependent on the density of the water. The density of salt water is greater than the density of fresh water. Let's look at the equation below. Buoyant force = Density * g * Volume of displaced water According to the equation, the buoyant force is directly proportional to the density. Since salt water is denser than fresh water, the buoyant force will be greater in salt water than fresh water. This force will push the ship up higher than if the ship was floating in fresh water. You could do this at home. Make a saturated solution of salt water. Then place a small wooden block into a glass of salt water. Use a ruler to measure the height of the fraction of the block that is above the surface of the salt water. Then place the block into a glass of fresh water and measure the height of the fraction of the block that is above the surface of the fresh water. You will see that the block is floating higher is salt water than in fresh water.
What makes ship not to sink in water?
It's the way how the ship is built. The ship in the water is able to fully displace water equal to it own weight, so that the water exerts a greater upthrust on the ship, than the ship is able to exert on the water with its weight. The net upthrust results in the ship staying afloat. If at any point the ship is not able to displace an amount of water equal to its weight, it will keep sinking until EITHER the ship finally displaces the right amount of water and begins to float OR the ship cannot displace enough water and becomes completely submerged, and sinks to the bottom of the body of water.
Why does a ship entering from fresh water to sea water sinks more?
You have it backwards. A ship floats higher in seawater than freshwater. This is because the dissolved salt makes seawater denser. due to the lack of salt content in fresh water. the salinity of ocean water makes it more dense, allowing the boat to sit higher in the water.
If a ship sinks is it displacing more or less water and why?
it is displacing more water imagine putting a rock into a small container of water. the container appears to have more water because it was displaced
What is a type of community where fresh and salwater mix?
Brackish water is where salt water and fresh water intermingle. If there is no current the salt water sinks to the bottom and creates an anaerobic layer which nothing can survive because of the toxins it produces therefore if a ship sinks in that environment it will be preserved for hundreds if not thousands of years. Look into shipwrecks that occurred in the Black Sea and the ancient trade route ship disasters. Ships have been brought up whole from the Byzantine Empire.
Will the ship sink further into the seawater than if it was in fresh water?
The ship will sink slightly. Salt water is denser there for heavy objects will float more in it. When the ship goes back to fresh water the density decreases and the ship lowers again. This link gives extra information and some simple experiments for you to try at home. http://www.kidsgen.com/school_projects/how_ships_float.htm
Is salty water more dense that salty water?
Salt water is more dense than fresh water. A ship would float higher at sea, and lower on a fresh water inland lake.
What is a ship wreck?
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.
Why water level in a ship decreases just before it sinks?
Because it loses weight when they decreases the water level of an ship
Why do needle sinks in water but ship floats?
Whether something sinks when it's placed on water is determined by the amount (weight) of water that it displaces. The needle, being small in size and relatively high in mass (relative to its size), displaces very little water when it is placed on the surface. The weight of the needle will be more than the weight of the water that it displaces and the needle will sink. The ship, though many times heavier than the needle, will displace alot more water than the needle. The ship will float if the weight of the displaced water is more than the weight of the ship.
If ship moves from fresh water to sea water then what happens?
i think it will rise slightly... according to Archimedes principle the weight of floating body is equal to water displaced by it.. and sea water has more density than fresh water and its weight will be more....so ship will slightly rise...
Can you write the name of objects that sinks in water?
Boats,ship,gravels.etc.
What is foundering of a ship?
A foundering ship fails to maintain its upright posture in the sea, takes on water, and sinks.
