probally fresh because no salt in mouth or eyes addition: it is easier to float/swim in seawater since seawater is denser than fresh water.
A ship floats higher in seawater compared to fresh water because seawater is denser than fresh water. The denser the liquid, the more buoyant force it exerts on the ship, causing it to float higher. This is due to Archimedes' principle, which states that the buoyant force acting on an object is equal to the weight of the fluid displaced by the object.
Salt water is denser than fresh water.
Seawater is denser than freshwater because it contains salt. The salt in seawater increases the mass of the water without significantly increasing its volume, making it denser. Temperature and pressure can also affect the density of seawater.
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.
salt water is denser
sea water is less denser than river water.
Because sand is denser than water. But I suspect you meant to ask "why is it easier to stay afloat in seawater than it is in fresh water". In which case the answer is the same: seawater is denser ... but not as dramatically, and the difference is small enough that you're unlikely to actually notice it unless you take careful measurements.
yes because of the salt
Blood is far denser than sea water as it has a whole bunch of cellular bodies mixed in with it. I think you wanted to ask "Which is denser seawater or serum?" In that case serum is still heavier even though it has less salt. Serum still has a wide assortment of exotic proteins dissolved in it.
Seawater is denser than freshwater because it contains dissolved salts and minerals, such as sodium and chloride, which add weight to the water molecules. These dissolved substances increase the overall mass of seawater and make it denser than freshwater.
The buoyant force from seawater would be greater than the force from freshwater. This is because seawater is denser than freshwater. This means that a clay shape which floats could carry a heavier load before sinking in seawater than in fresh water.
