Why do eggs float in salt water?

According to physical knowledge, F float = ρ gV row of liquid \x0d\ρ liquid density \x0d\V The volume of discharged liquid is equal to the volume of the object immersed in the liquid (suspension and sedimentation: the whole object is in the liquid, and V row is equal to the volume of the object; Floating: Some objects are in liquid, and row V is equal to the volume of the submerged object) \x0d\ When the volume of the egg is constant and the density of the liquid increases, the buoyancy increases accordingly. Adding salt to water will increase the density of liquid, so eggs will float in salt water. In other words, if the density of salt water is greater than that of eggs, the eggs will float; If the density of salt water is equal to the density of eggs, eggs will be suspended in liquid; If the density of salt water is less than that of eggs, the eggs will sink.
