Eggs, water, floating.

An egg doesn't float in fresh water but since salt water is more dense than fresh water, it has a better chance of floating in the salt water. The greater buoyant force allows the egg to float in the salt water, if salty enough.

More explanation

An egg sinks in fresh water but not in salt water because fresh water is not as dense. In order for something to float, the buoyant force has to be greater than or equal to the weight of the object. The buoyant force is equal to the weight of the liquid that is displaced by the object. To figure out the weight of the water displaced you multiply the density of the water by the volume and then multiply that by gravity. The density of the fresh water is less than the density of the salt water, therefore the weight of the water displaced will be greater in the case of the salt water, resulting in a greater buoyant force.

The more salt in water the more bouyant an object becomes. The salt makes the water more denser. Check out the dead sea. Most salt content in any lake or sea. The density of the salt water is greater than the density of the egg. Items sink if their own density is greater than the density of whatever they are trying to float in. Items float to the top if their density is less than the density of what they are floating in, and items hang in the middle if the densities are the same. Adding in the salt gives the water a greater density than the water did had before, so the egg doesn't float in freshwater.

A fresh egg will sink in fresh water but it will float in salty water. A rotten egg will float in fresh water.

Compounds that float or sink in fresh water?

At 4°C pure water has a density (weight or mass) of about 1 g/cu.cm, 1 g/ml, 1 kg/litre, 1000 kg/cu.m, 1 tonne/cu.m or 62.4 lb/cu.ft Everthing else that is above 62.4 lb/cu.ft will sink, anything below will float.


What are 2 differences between salt water and fresh water?

Salt water has a higher salinity level compared to fresh water, which makes it denser and allows objects to float more easily. Fresh water has a lower freezing point than salt water, allowing it to freeze at a higher temperature.


Experiments using salt water and fresh water?

Experiments comparing the densities of salt water and fresh water can demonstrate how salinity affects the buoyancy of objects. Salt water is denser than fresh water due to the dissolved salt, causing objects to float higher in salt water compared to fresh water of the same volume. This phenomenon is demonstrated in experiments such as the floating egg or sinking and floating objects in different types of water.


How can you tell the difference between salt water and fresh water?

One way to differentiate between salt water and fresh water is by taste; salt water has a distinct salty taste due to its high mineral content, while fresh water tastes neutral. Additionally, salt water is denser than fresh water, so objects will float higher in salt water compared to fresh water. Conductivity tests can also be used to distinguish between the two types of water.


Why is salt water so dense?

Salt water is denser than fresh water because salt increases the mass of the water by adding more particles to it, which makes the water heavier and more tightly packed. This increased density allows objects to float more easily in salt water compared to fresh water.

What can float in salt water but sink in fresh water?

i think it is ppeople because they float in salt water and sink in fresh water.


Is it eaiser to float in salt water than fresh water?

Yes, it is easier to float in salt water than in fresh water due to salt water's higher density. The salt content in the water increases its buoyancy, making it easier for objects and people to float on the surface.


Is it easier to float in salt water or fresh water?

It is definitely easier yo float in salt water.


Why does salt water float on fresh water if it is denser than fresh water?

Assuming equal temperatures it does not. The fresh water will be on top.


Dose a swimmer float better in fresh salt water or non fresh salt water?

on fresh salt water


Do boats float differently on fresh water vs salt water?

Yes, salt water is denser than fresh water so boats float higher in salt water.


Why is it easier to float in saltwater than in fresh water then in fresh water?

Because salt is dense, so denser the water the better you float!


How do objects float differently in salt water than in fresh water?

Objects float higher in salt water compared to fresh water because salt water is denser than fresh water. The higher density of salt water provides more buoyant force, causing objects to float higher. Additionally, salt water can also affect the rate at which objects sink or float due to changes in the water's viscosity and surface tension.


Do objects float more in salt water or fresh water?

Objects float more in salt water compared to fresh water because salt water is denser. The increased density of salt water provides greater buoyancy for objects, allowing them to float more easily than in fresh water.
