Eggs float in salt water because salt water has a higher density than fresh water. The buoyant force acting on the egg is greater in the denser salt water, causing it to float.
Salinity and temperature both affect water density. As salinity increases, water density also increases because salt water is denser than freshwater. Similarly, as temperature decreases, water density increases due to the water molecules becoming more tightly packed together.
Salt water has a higher density than fresh water. Fresh water is only made up of two things, hydrogen and oxygen. Salt water is made up of hydrogen oxygen sodium and chlorine, which gives it a higher density.
d) Water has the lowest density among the options listed.
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.
more salt means more density so more buoyancy.
The salt water has a greater density and the floating is easier.
Because the salt is an impurity it raises the boiling point by density differences
No salt has a greater density.
Salt water density really depends on a few different things. The concentration of salt and temperature are the 2 largest factors in determining the density of salt water.
When salt is put into water, it dissolves and exists in the water as sodium and chlorine ions. One effect of these ions is: the water conducts electricity more easily. Another effect of salt in water is the freezing temperature lowers. Another effect of dissolving salt into water, is the density increases. This is due to mass being added, while the volume hardly increases.

well when the salt dissolves into the water it makes water considerably denser and there for the water can hold more weight by:Matthew Shouse
The density of a salt water solution compared against the densities of "pure" water and salt provides an approximate value of the ratio of water to salt in the mixture.
Yes, fresh water has a slightly lower density than salt water.
Salt water has a higher density than the egg.
