Probably a chicken.
SaltWater
yes
yes, it can even float with heated water.
Saltwater is denser than freshwater, so when you add salt to water, the water becomes more dense. When you place an egg in saltwater, it floats because the density of the saltwater is higher than the density of the egg, causing it to float instead of sink.
cuz saltwater is more dense than freshwater
Eggs can float in saltwater because the high density of saltwater makes the overall density of the egg lower than that of the water, causing it to float. In freshwater, the egg is denser than the less dense water and therefore sinks.
Because the density of the egg is lower than the density of the saltwater Because the density of the egg is lower than the density of the saltwater
Objects that contain a higher density that water will sink, but if the same object has a lower density that saltwater, then it will float in salt water. And this also depends on the concentration of sodium ions present in the salt water. As the concentration of the sodium ions increase, the density of the salt water increases.
A raw egg gets lighter when placed in saltwater due to the process of osmosis. The saltwater has a higher concentration of solutes compared to the liquid inside the egg, causing water to move out of the egg through the semi-permeable shell. This loss of water from the egg makes it less dense and gives the appearance of being lighter in the denser saltwater. Consequently, the egg may also float in saltwater, as its buoyancy increases.
If you drop an egg in saltwater, it will float due to the higher density of the saltwater compared to the egg. The salt increases the water's density, making it more buoyant, allowing the egg to rise to the surface. In contrast, an egg typically sinks in fresh water because it is less dense. This phenomenon illustrates the principles of buoyancy and density.
About 6 tablespoons - Check out the link below It depends on how old the egg is. An egg that is a week or so old will float in tap water...that's how you can test to see if an egg is fit to eat.
This is unknown and the information lost to antiquity.
