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.
because of the density
Thumb tack sinks in water and floats in mercury.
Very much so … Ice Floats, Gold Sinks.
It floats or if it sinks it is fresh and if it goes in the middle it could be rotten or not it depends
The iron and sulphur split because the iron sinks and the sulphur floats so you can separate the mixture
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).
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
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.
sinks
It is impossible to tell; whether an object floats or sinks depends on its density, not on its weight.
Not Yassine JR
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
Styrofoam floats on water, Soap sinks.
The Density.
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.
A submarine sinks as it fills its' ballast tanks with water. Then it uses pressurized air to empty them and float again.
Iron has a higher density than water, so it sinks in water; but is less dense than mercury so it floats.
A peeled orange floats A not peeled orange sinks
