Why does seawater have a greater buoyant force than fresh water?

Seawater has a greater buoyant force than fresh water because seawater has a higher density than fresh water therefore the buoyancy is higher.
*Improved*
This happens because when water mixes with the salt in sea water, the density changes to the average density which is around 1.55 g/mL (Average density is the density of different materials put to together )

What fraction of the Worlds fresh is frozen?
If it is fresh it is not frozen, and if it is frozen, it is not fresh. so the answer is simple: 0%If it is fresh it is not frozen, and if it is frozen, it is not fresh. so the answer is simple: 0%If it is fresh it is not frozen, and if it is frozen, it is not fresh. so the answer is simple: 0%If it is fresh it is not frozen, and if it is frozen, it is not fresh. so the answer is simple: 0%

How many fresh apples equal one cup of dried apples?
Roughly 4 dried apples equals one cup.
Ninety-seven percent of the world's water resources are found in what?
fresh water
What is the mass of 25 ml of water?
For fresh water at room temperature, it is 25 grams
How would the buoyant force acting on the floating clay shape change if it were immersed in seawater?
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.
Why a grape didn't float in fresh water and why a grape didn't sink in salt water?
Salt water is much denser than fresh water and therefore can provide a much greater buoyant force.
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.
Why does an egg sink in fresh water but floats in salt water?
Eggs, water, floating.An egg doesn't float in fresh water but since salt water is more dense than fresh water, it has a better chance of floating in the salt water. The greater buoyant force allows the egg to float in the salt water, if salty enough.More explanationAn egg sinks in fresh water but not in salt water because fresh water is not as dense. In order for something to float, the buoyant force has to be greater than or equal to the weight of the object. The buoyant force is equal to the weight of the liquid that is displaced by the object. To figure out the weight of the water displaced you multiply the density of the water by the volume and then multiply that by gravity. The density of the fresh water is less than the density of the salt water, therefore the weight of the water displaced will be greater in the case of the salt water, resulting in a greater buoyant force.The more salt in water the more bouyant an object becomes. The salt makes the water more denser. Check out the dead sea. Most salt content in any lake or sea. The density of the salt water is greater than the density of the egg. Items sink if their own density is greater than the density of whatever they are trying to float in. Items float to the top if their density is less than the density of what they are floating in, and items hang in the middle if the densities are the same. Adding in the salt gives the water a greater density than the water did had before, so the egg doesn't float in freshwater.Did you know?A fresh egg will sink in fresh water but it will float in salty water. A rotten egg will float in fresh water.

Why does buoyancy force change in the fluid temperature high temperature less buoyancy low temperature high buoyancy now why is that?
Buoyant force is directly proportional to the mass of the liquid that is displaced by an object that is submerged in it. The mass of a certain volume of a liquid is directly proportional to the density of that liquid. The more dense the liquid is, the greater is the buoyant force. For water that is over 4 degrees Centigrade in temperature, the warmer the water, the less dense is the water. In other words, warm (summer) water is less buoyant than is cold (winter) water, because the density of warmer water is less than is the density of cooler water. Similarly, salt water is more buoyant than fresh water, because the density (in grams per cubic centimeter, or pounds per cubic yard) of salt water is greater than is the density of fresh water.
Why is it easier to swim in seawater then it is to swim in fresh water?
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.
How much seawater is there versus fresh water?
97% seawater, other 3% is freshwater.
How do you separate fresh water from seawater?
by evaporation
Is the Gulf of Oman fresh water?
No, it is seawater.
How does salinity affect floating objects?
Increasing the salinity of fresh water makes the water denser. The denser the water the less deeply an object will sink into the water. The very saltiness of the Dead Sea, means that people can float on the surface without effort. A ship, after displacing its weight, will float higher on the ocean, than it would if sailing on fresh water.
What is the concentration of salt in seawater and the specific heat capacities of sea water and fresh water?
the seawater smells
