Q8 of 16 Page 26

Can egg be floated on water? Find out through an activity.

The density of an egg is more than water. So the buoyant force (upthrust due to water displaced by it) is not large enough to counter the weight of the egg. But if you add some salt to the water, its density increases. Now the density is high enough for the buoyant force to outweigh the weight of the egg and thus it floats.
