An egg sinks in soft water but floats in a concentrated solution of salt because?
Correct answer: C. the density of salt solution exceeds the density of eggs
- A. egg absorbs salt from the solution and expands
- B. albumin dissolves in salt solution and egg becomes lighter
- C. the density of salt solution exceeds the density of eggs
- D. water has high surface tension
Explanation
An object floats when the liquid's density is greater than the object's average density. Concentrated salt solution is denser than the egg, whereas fresh water is slightly less dense, so the egg sinks in fresh water.
