  2. False

A Correct answer
Explanation

An egg sinks in tap water because its density is greater than water. In a concentrated salt solution, the water becomes denser than the egg due to dissolved salt, causing the egg to float. This demonstrates the principle of buoyancy and Archimedes' principle.

AI explanation

An object floats or sinks in a fluid based on relative density: since a concentrated salt solution is denser than plain tap water, the buoyant force it exerts on the egg becomes strong enough to exceed the egg's weight, causing it to float. In plain tap water, the egg's density is greater than the water's, so it sinks.
