Question

An egg sinks in pure water and flot in salt water why

Answer 1

the salt water would be able to hold the egg up better than the fresh water due to density. ... Salt solution is more dense than the contents of the egg. If there is not enough salt in the water, they will not float. The salt itself is more dense than water, but it loses density as it dissolves.

Answer 2

The density of the egg in the salt water is more than the weight of egg so it floats

Whereas in pure water the egg's density is more than water
