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.
Yes, molasses is denser than water, so it typically sinks rather than floats on water.
Wax typically floats on water due to being less dense than the water. However, the specific gravity of wax can vary depending on its composition and temperature, which might affect whether it sinks or floats.
A diluted solution of bleach (sodium hypochlorite) is commonly used to disinfect surfaces like sinks, tabletops, and food equipment. Follow the manufacturer's instructions for proper dilution and contact time to ensure effective disinfection.
no, magnesium never floats in acids...........
To carry out a hair porosity test, take a few clean strands of hair and place them in a bowl of water. If the hair sinks quickly, it has high porosity. If it floats, it has low porosity. If it floats in the middle, it has normal porosity. This test helps determine how well your hair absorbs and retains moisture.
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
An egg that sinks in water is fresh, while an egg that floats is not fresh.
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.
