When you place an egg in water, it sinks. If you add salt to the water, after some time the egg floats. Choose the correct explanation

A. Adding salt to the water increases its density When the density of the water matches that of the egg, the egg becomes neutrally buoyant and floats

B. Adding salt to the water decreases Its density When the densily of the water matches that of the egg, the egg becomes neutrally buoyant and floats

C. Adding salt to the water decreases its volume When the volume of the water matches that of the egg, the egg becomes neutrally buoyant and floats

D. Adding salt to the water increases ts volume When the volume of the water matches that of the egg, the egg becomes neutraly buoyant and floats

B

Explanation:

This happens because adding salt to the water decreases Its density. When the density of the water matches that of the egg, the egg becomes neutrally buoyant and floats.

The weight of the egg becomes equal to the upward buoyant force by the water on to the egg and hence, the egg floats.
