An egg sinks in fresh water but floats in highly salty water. Why?

Answer 1

If we add salt into the fresh water . It Will became more denser then egg & the egg will start to float . Dead sea works on same principal .

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 stats to float in water.
