Question

Mary, while examining whether a boiled egg sinks or floats, found that it floats but Vakula made it sink, How is it possible? Guess and write it.

Answer 1

Mary’s water contained more salt than Vakula’s water. Therefore Mary’s egg floated.

Answer 2

Answer:

The boiled egg normally has more density than water and thereby it sinks. However, if salt is added to the water, then it becomes denser and in such cases, the egg floats in the water.

So, from this, we can conclude that Mary was trying to test it using water that had high salt concentration. However, Vakula made it sink by changing the water by lowering the salt concentration.
