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

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.

A fresh egg will sink in fresh water but it will float in salty water. A rotten egg will float in fresh water.

∙ 11y agoIt's all a matter of specific gravity. The egg floats in salt water, because salt water has a higher specific gravity. Adding fresh water to the salt water lowers the specific gravity and allows the egg to sink. Add enough fresh water (or have no salt water) and the egg will sink.

What happens to egg when soaked in water?
It floats or if it sinks it is fresh and if it goes in the middle it could be rotten or not it depends
Does an egg float in water with flour?
In a mixture of oil and water, the two will separate with the oil on top. If the water has enough solute in it (salt, sugar), the egg will float in the water, but not above the oil. An egg is denser than fresh water, but less dense than salt water. It is denser than most oils.
What happens to the density of a diamond submerged in water?
A diamond is a solid, while water is a liquid.
What is the densest cold salt water warm salt water cold fresh water warm fresh water?
Cold Salt Water is the densest. When there is less heat in a liquid, the particles are closer together. The salt also saturates the water and makes it even denser. That's why boats float better in Cold Salt Water than in Warm Fresh Water. P.S. Next time, put commas between the options. -------------------------------------------------------------------------------------------------------- Sources: Grade 8 Science
Can you put salt in water to make an object float?
If the object does not quite float in water, adding salt to the water might make the object float, yes.
If you float in salt water what will you do in fresh water?
If you just barely float in salt water, you will sink in fresh water.
Is it eaiser to float in salt water than fresh water?
It is easier to float in salt water than in fresh water.
What can float in salt water but sink in fresh water?
i think it is ppeople because they float in salt water and sink in fresh water.
How do objects float differently in salt water than in fresh water?
the salt makes the water denser then the fresh water so it is easyer to float in.
Will ships float or sink in fresh water?
Ships float in fresh water too. Only a little deeper, since fresh water is less dense than salt 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.
Does salt water float over fresh water?
no< fresh water will become mixed with the salt water
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.
Is it easier to float in salt water or fresh water?
It is definitely easier yo float in salt water.
Why does salt water float on fresh water if it is denser than fresh water?
Assuming equal temperatures it does not. The fresh water will be on top.
Dose a swimmer float better in fresh salt water or non fresh salt water?
on fresh salt water
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.
