Question

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

Upthrust in Fluids Archimedes' Principle and Floatation Class 9 ICSE

March 20, 2024

Answer

A strong salt solution is denser than fresh water (i.e. density of strong salt solution is more than that of fresh water), hence it will exert more upthrust on the egg that balances the weight of the egg. Therefore, the egg floats in strong salt solution and sinks in fresh water.
