CHAPTER 1 HOMEWORK
1.1) What is the definition of nanotechnology?
Nanotechnology is the control of matter measuring between 0.1 to 1000 nanometers.
It means engineering things at the atomic, molecular and macromolecular scales.
1.2) The number 1,234,567 written out is one million, two hundred thirty four thousand,
five hundred sixty seven. Write out this number: 1,200,300,400,500,600,700,800,901
One septillion, two hundred sextillion, three hundred quintillion, four hundred
quadrillion, five hundred trillion, six hundred billion, seven hundred million, eight
hundred thousand, nine hundred and one
1.3) Rank the following things from largest to smallest: polio virus, drop of water,
mercury atom, e coli bacterium, helium atom, human red blood cell.
Drop of water, human red blood cell, e coli bacterium, polio virus, mercury atom,
helium atom
1.4) The concept of the atom was introduced approximately how long ago?
2,500 years ago
1.5) What are the three main components of an atom?
protons, neutrons, and electrons

1.6) What are the main components of an atom’s nucleus?
neutrons and protons
1.7) What is the Law of Definite Proportions?
In a pure compound, the elements combine in definite proportions to each other
1.8) What is the Law of Multiple Proportions?
Elements combine in the ratio of small whole numbers. (For example carbon and
oxygen react to form CO or CO 2 , but not CO2.3.)
1.9) Boyle’s law states that PV=C, where P is the pressure of a gas, V is the volume and
C is a constant (assuming constant temperature). Consider a gas held in a 4 m3 container
at 1 kPa. The volume is then slowly doubled. (a) What is the new pressure? (b) Use
atoms to explain how a larger container leads to a lower pressure.
ANSWER
A) ½ of the original pressure = 0.5 kPa
B) The pressure is nothing more than the individual gas molecules colliding over
and over again with the container walls, exerting a force per unit area. If you make
the volume of a container larger, the molecules’ collisions with the wall will occur
less frequently. This means that the pressure will decrease.
