Try to float an egg in water. Then dissolve salt in the water until the egg floats. How does the density of an egg compare with the density of tap water? Salt water? How do you know?
To compare: Density of an egg with density of tap water and salt water .
Answer to Problem 62A
The density of egg is more than tap water but less than salt water.
Explanation of Solution
Introduction:
Density is defined as mass per unit volume. The object having lesser density than water can float on water whereas the object having more density than water will sink.
When an egg is put in a bowl containing tap water, it will sink. This indicates the the density of egg is more than the density of tap water. Thus, egg is more dense in comparison to tap water.
Now, add some salt in a bowl of tap water . It is observed that the egg starts floating. This indicates that density of salt water is more than the density of egg. Thus, egg is less dense in comparison to salt water.
Conclusion:
Therefore, density of egg is more than tap water but less than salt water.
