Explain the following :
An egg sinks in fresh water, but floats in a strong salt solution.

उत्तर
Density of a strong salt solution is more than the density of fresh water. Hence, the salt solution exerts a greater upthrust on the egg which balances the weight of the egg, so the egg floats in a strong salt solution but sinks in fresh water.
