Chapter 15, Problem 5TE

Does it make sense to say that this text book is more that $99.9\%$ empty space? Defend your answer.

To determine

Whether the $99.9\%$ space of this textbook is empty.

Answer to Problem 5TE

The $99.9\%$ of this textbook is empty space because the atoms of the textbook occupies only 0.1% space of this textbook.

Explanation of Solution

The basic particles of an atom are electron, proton and neutron. The size of these basic particles is very small, so that these particles cannot be observed with naked eyes. It is too much smaller than the wavelength of the visible light.

The basic particles of the atom are very small, so they occupy very little space. The maximum part of the atom is empty space.

The atoms are also very small than the size of this textbook. The atoms only occupy $0.1\%$of the total size of this text book, so $99.9\%$ of this textbook is empty space.

Conclusion:

Therefore, the 99.9% of this textbook is empty space because the atoms of the textbook occupies only 0.1% space of this textbook.
