How does density and salt make an egg float?

Answer 1

Regular water is not dense enough to make an egg float. The egg is slightly MORE dense than the water around it, so the egg sinks. However, when you ADD salt to the water, it makes the water MORE dense than the egg. Now that the egg is less dense than the saltwater surrounding it, it will float ! The same thing happens with people...if you happen to live near saltwater AND freshwater (a swimming pool will do just fine), go lay on your back in the freshwater without moving your arms and legs, and just take a big breath and hold it....you will probably sink a little bit (at least your legs might). Now do the same thing in the saltwater....you will float like a bobber !

There are other properties at work on the egg though too...like "displacement". That is what makes a big ol ship made of steel float....but that is another story....

Hope this helps !

Answer 2

by way of including salt to water, it made the water exchange into denser. A denser liquid might actually help products with extra weight than a much less dense liquid might. The salt water is denser than the easy water. once you place the egg interior the salt water, it is waiting to decide for the flow. comparable ingredient occurs as quickly as we interior the sea, we decide for the flow around extra undemanding than if we've been in a extensive-unfold swimming pool. The salt water is denser than swimming pool water making it extra undemanding to help our weight. as quickly as we are in salty water, we decide for the flow extra actual or experience extra buoyant.
