The egg sinks in fresh water but floats in salty water. explain why?

An egg, which is in a liquid, is acted upon by 2 forces: the force of gravity m * g, directed vertically downward, and the buoyancy force of Archimedes Farch, directed vertically upward.

The force of Archimedes is determined by the formula Farch = ρ * q * V, where ρ is the density of the fluid in which the body is immersed, g is the acceleration of gravity, V is the volume of the immersed part of the body in the fluid.

In fresh water, the force of gravity is greater than the force of Archimedes, so the egg sinks to the bottom.

The density of salt water is greater than that of fresh water, therefore, in salt water, the strength of Archimedes is greater than in fresh water. The force of gravity is balanced by the force of Archimedes, so the egg floats in salt water.
