An egg sinks in fresh water but floats in a strong solution of salt why?

because following the density principle, the density of the egg compared to the density of the tap water is lesser....(the density principle states that an object or substance with lesser density will float on the surface of the substance or object which has the greater density...).....now,,,with salt,,, salt makes the density of the tap water to increase and increases also the salinity of the water making the egg float because the density of the water with salt is now greater than the density of the egg....
An egg will float when the density of the water is greater than the density of the egg. Adding salt increases the density of a salt water solution. Whether the egg floats or sinks depends on the condition of the egg as well as the amount of salt in the water. If an object is LESS dense than the solution that it is in, then it WILL float. If an object is MORE dense than the solution it is in, then it WILL NOT float.
An egg is more dense than regular water; therefore, the egg will sink. But when you add salt to the water, you are making the solution more dense. The salt water's density becomes greater to the point that it is more dense than the egg. Because the egg is now LESS dense than the water, it floats.

Does a thumb tack float or sink?
Thumb tack sinks in water and floats in mercury.
Is gold denser than ice?
Very much so … Ice Floats, Gold Sinks.
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
What happens to iron and sulphur when you add water?
The iron and sulphur split because the iron sinks and the sulphur floats so you can separate the mixture
How can you tell if one substance will float in another substance?
Weigh samples of the two that have the same volume. A solid object with greater "average density" will sink in a less-dense fluid. A lighter fluid will float atop a heavier one if they do not form a solution. Examples: - One cc of metallic iron will weigh more than one cc of motor oil (sinks) but less than one cc of mercury (floats in the mercury). - One cc of mercury weighs more than one cc of water (sinks) but one cc of oil weighs less than the water (floats).
Explain why an egg sinks in fresh water but floats in a strong solution of salt?
One substance will float on another if its density is less. By adding salt you are increasing the density of the solution. As you add salt, at some point the density of the solution will reach and then exceed the density of the egg
How long can a farm fresh egg be out of refrigration?
It all depends really, but if you put the egg in cold water you will get your answer. If it floats its rotten and if it sinks its still a farm fresh egg.
Which one has more density the one that floats or sinks?
sinks
Which object weighs more a can that floats or a can that sinks?
It is impossible to tell; whether an object floats or sinks depends on its density, not on its weight.
What sinks in water sinks to the bottom then floats again?

How does an air craft carrier float in fresh water when a penny sinks in fresh water?
aboat floats because it displaces it,s weight in water when that happens it stops sinking a penny cannot displace it,s weight in water so it sinks hope you understand
Soap or styrofoam which one floats?
Styrofoam floats on water, Soap sinks.
What determains if an object floats or sinks?
The Density.
How do you make sure you purchase fresh eggs?
You can tell if eggs are old by dropping one in a cup or bowl of water. If the egg floats, it is bad. If it sinks, it is good.
How does a submarine works that floats then sinks and then again floats?
A submarine sinks as it fills its' ballast tanks with water. Then it uses pressurized air to empty them and float again.
Why iron nail floats on mercury but sinks on water.?
Iron has a higher density than water, so it sinks in water; but is less dense than mercury so it floats.
