Question

A fresh egg sinks in pure water but floats in saline water because

Answer 1

The fresh egg sinks in fresh water and floats in salt water. The salt water is denser than the fresh water therefore; the egg which is less dense than salt water will float!

The ability of something, float in water or some other liquid is known as buoyancy.

The density of salt water is more than that of fresh water which results in more buoyancy.

The density of the egg is higher than the density of tap water, so it sinks.

When salt is added to the water, the saltwater solution's density becomes higher than the egg's, so the egg will then float.
