Salt water has a higher density than fresh water. Fresh water is only made up of two things, hydrogen and oxygen. Salt water is made up of hydrogen oxygen sodium and chlorine, which gives it a higher density.

Does freshwater have a lower density than salt water?

Yes, fresh water has a slightly lower density than salt water.


Why does an egg sink in fresh water but float in salt water but stays in the middle when pour water into 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.


How does an salt make an egg float?

The separate layers formed because salt water is denser than pure water. Fresh water has a density of about 1.0 gram per ml of volume. Matter with higher density will sink in water; matter with lower density will float on top.The density of an egg is between that of water and salt water, so in your beaker, the egg balanced between the two layers.


What are 2 differences between salt water and fresh water?

there is salt in salt water and little salt in fresh water


Which type of water freezes first fresh or salt water?

Fresh water freezes at a higher temperature than Salt water. So Fresh Water doesn't have to lose as much heat in a given amount of time in order to Freeze.

Does toys float better on fresh water or on salt water?

No. Toys float better on salt water than on fresh water because salt water has higher density, and the ratio of density controls buoyancy.


Is it quicker to swim in salt water or fresh water?

Salt water has a slightly higher density, so it will be a little quicker to swim in fresh water.


Why can we float easier in the sea than in a freshwater lake?

The density of salt water is higher than fresh water.


Why can a person not float in fresh water but can in salt water what does that tell us about the density of salt water?

Salt water has higher density than the body of a person who floats on it, but the person's body may sink in less dense fresh water.


Why is it easier to float in the ocean than fresh water?

Because salt water has a higher specific density than fresh water.


Why does salt water make stuff float than fresh water?

Salt water has a greater density than fresh water. So the same object will foat higher in salt water than in fresh, and some things will foat in salt water that are too dense to float in fresh water.


Does objects that float in water float in salt water?

Yes. Salt water has a slightly higher density then fresh water which means its a little easier for things to float in salt water. So if it floats in fresh water it will certainly float in salt water.


What is the densities of fresh water and salt water?

Salt Water Density: 1.027 g/mL Fresh Water Density: 1 g/mL


Why do ship float better at sea than in fresh water?

Sea water has salt, and therefore a higher density.


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.


Does Egg Float In Salt Water Or Fresh Water?

Fresh eggs float in salt water because the density of salt water is more than the density of the egg. But fresh eggs do not float in fresh water because the density of water is less than that of the egg. Salt increases the density of water.


Why does freshwater float on saltwater?

Salt water is denser hence HEAVIER then fresh water, Salt Water has a density of 1.02g/ml and Fresh Water has a density of 1.00g/ml.
