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.
Yes, salt water is denser than fresh water so boats float higher in salt 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.
Ships, boats, anything buoyant, really...
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.
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.
It is easier to float in salt water compared to fresh water because salt water is denser. The added buoyancy from the higher density of salt water makes it easier for objects to float.
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.
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.
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.
An egg will float in salt water because the increased density of the salt water makes it more buoyant. In tap water, the egg will sink due to the lower density of the water compared to the egg.
The floating or sinking of an object depends on the upthrust force the water exerts on the object. By Archmides' principle, Upthrust Force = (Density of Liquid) * (Volume of Liquid Displaced by the object) therefore the upthrust force depends on the density of the liquid, and as salt water has a larger density than fresh water, boats should float better on salt water.
