Salt water is denser than pure water.
An egg will sink in water but will float in salt water. An egg will sink faster in hot water than it will in cold water.
An egg will float in salt water because the salt makes it denser and allows the egg to stay near the surface. But in regular water it will sink straight to the bottom.
Salt water. Salt water is very hypotonic and will force the egg to float. Regular water is hypertonic and force water in. Causing the egg to sink like the Titanic.
How much salt water is present is not important, the problem is what is the concentration of salt in the water. The saltier it is, the denser the salt water becomes. If the salt water is denser in comparison to the density of the egg (which will more or less vary with each egg), then the egg will float; if not, then the egg will sink.
A Rock would obviously sink in water and a egg would float in salt water Believe it or not bowling balls that are denser than water float!
Normaly if an egg floats it is bad and should be discarded. As the egg ages air pockets enter the egg, that's why they float. A change in buoyancy. If the egg is more dense then the water (or whatever liquid it is in), it will sink.
why does an egg float or sink in water
If the egg is good and not spoiled it will sink down. If the egg is spoiled it will float up.
By adding salt to water, you are increasing the density of the water (essentially how much "stuff" that is in the water). When the density of the salt water becomes greater than the density of the egg, the egg becomes more positively buoyant and will float instead of sink.
It sinks because the water is more dense than the egg in the water.
Yes, and egg will float in salt water.
An egg will sink in fresh water. Salt water is denser than fresh water, which allows the egg to float.
