A fresh egg when placed in salt water will
Sink and go to the bottom
Sink but will not go to the bottom
Float
Burst
Float
Adding salt to the water increases the density of the solution because the salt increases the mass without changing the volume very much. When enough salt is added to the water, the saltwater solution’s density becomes higher than the egg’s, so the egg will then float.
