Why do ships sink more in fresh water than in salt water in respect to freeboard?

It is because the fresh water has less density compared to that of salt water.

What are the differences between salt water and fresh water?
the difference between salt water and fresh water is that salt water is from the ocean and fresh water is water that hasn't gotten to the ocean and so the water is clean, And you can only drink fresh water not salt water
What is the difference between fresh water and potable water?
the difference between fresh water and potable water is fresh water can come form the ground, and/or, ice burgs.
Does salt water clean better than fresh water?
Fresh water ..... lol
Where are fresh water ecosystems located?
Fresh water ecosysystems are located in every continents.
When will fresh water run out?
This is a somewhat misleading question. Water is a renewable resource, so the 3% of our water that is fresh water will remain fresh water. If we consume the water, it is recycled and returned to the system. Salt Water also becomes fresh water through the natural rain and weather cycles of our planet. The only issue we would have is if we started to pollute and destroy existing water systems used for drinking and irrigating our fields. This would still be considered fresh water, but unusable water.
Why do ships sink more in fresh water than in salt water in respect to?
Salt water is more dense than fresh water. So when you're in salt water you float more than when you are in fresh water
Will ships float or sink in fresh water?
Ships float in fresh water too. Only a little deeper, since fresh water is less dense than salt water.
Why was water important on ships?
Humans cam survive for about 3 days with out fresh water. Fresh water is brought on ships for this reason because distilling salt water on a ship is difficult.
Why do boats float and ships sink?
Provided the boats and the ships displace their weight in water without the water coming inboard, they will float and not sink. A boat made of wood is likely to float even when full of water because wood tends to float. It is all to do with displacement and freeboard.
Why freeboard required for water tank?
To avoid any overflow
Density - ability for a boat to float?
It is the displacement of the vessels weight and the freeboard remaining of a vessel that determines whether a vessel will float and or sink. A ship will float higher on salt water (salt water is denser) than if on fresh water (less dense).
Do ships in the general lakes need more or less ballast than ocean-going ships?
Ships need more ballast in the ocean because the salt helps to keep them a float.What we know is that salt water is about 3% more dense than fresh water and that ships use the water they are floating in for ballast.Say an ocean ship needs 10 tonnes of ballast to get to it's stable water line. The volume of 10 tonnes of seawater would equal 9.7m3.That same ship will float slightly lower in fresh water since fresh water is less dense. It will need 3% less ballast weight (9.7 tonnes) to get to the same stable water line in fresh water. The volume of 9.7 tonnes of fresh water would equal 9.7 m3.So, the ship in the ocean requires 3% more ballast weight than the ship in fresh water, but the ballast volume is the same in both cases.
Why do ships float higher on sea water than in fresh water?
Because the the sea water contains salt, which increases the density of the water. Therefore, the ships becomes even less dense than the water, making it float higher.
Why is it easier to swim in salty water than in pure water?
Salt water is denser that fresh water, so a swimmer (and ships) float higher in saltwater.
How does a boat keep water out of it?
By having sufficient freeboard once the vessel's gross weight has been displaced. Freeboard is the height from water surface to the lowest point of the walls (gunnel) of the vessel. Any water that does come inboard (spray or wave over the side) needs to be pumped out of the vessel.
What is a part of a yacht that is under water?
"all boats" have a draft, the part beneath the water. The part above is the freeboard. The part in the water is the Hull.
Would a large metal ship float in the same volume of fresh water?
Metal ships are built to float.
