Because according to the principle of Archimedes: "Any body immersed in a liquid undergoes a bottom-up thrust equal to the weight of liquid displaced"
When submerged, the boat displaces water.
Since salt water has greater weight per unit volume (density) than fresh water, the weight of the displaced salt water is higher. So the ship receives a bigger push in salt water than in fresh water. So it floats more.
What else can I help you with?
Do boats float differently on fresh water vs salt water?
Yes, salt water is denser than fresh water so boats float higher in salt water.
Why do boats float better in salt water rather than fresh water?
flotation is due to the fact the boat is less dense than the water, salty water is more dense than normal water. Consequently things can be heavier or more dense and still be less dense than water aka they float.
What objects float in salt water?
Ships, boats, anything buoyant, really...
How do objects float higher in salt water?
Objects float higher in salt water due the density caused by the salt, the more salt present in the water the higher the object will float.
Do objects float more in salt water or fresh water?
Objects float more in salt water compared to fresh water because salt water is denser. The increased density of salt water provides greater buoyancy for objects, allowing them to float more easily than in fresh water.
Is it easier to sink or float in salt water?
it is easier to float, salt water has a higher density. The more salt, the easier it is to float.
Do you float in salt water or fresh water which on is more dense?
Salt
Does an egg float in water mixed with salt?
An egg does float in water that is mixed with salt, because salt provides more density in the water, and ,therefore, allows an egg to float.
Does salt float in water?
Yes, salt can make water denser, causing objects to float more easily.
Do you float or sink in salt water?
You are more likely to float in salt water than in freshwater due to the increased density of salt water. The salt makes the water denser, providing more buoyancy and making it easier for objects, including humans, to float on its surface.
Will an egg float in salt water or tap water?
Eggs float in salt water but not in tap water, which is a fresh water. This is because salt water is more dense than fresh water.
Why do you float better in the sea?
The more salt there is in water the more buoyant an object is. The salt makes the water dense. Objects only float if they have less density than salt.
