The actual diameter of an atom is about a tenth of a nanometer
(10
(mostly N and O ) at room temperature and a pressure of one
atmosphere -- 10 Pa.
1. Calculate the number of molecules in the sample of
gas.
2. Estimate the average spacing between the molecules.
3. Estimate the average speed of a molecule using the relation
between the KE of a
molecule and the temperature.
4. Suppose that the gas were rescaled upwards so that each
atom was the size of a tennis
ball. What would be the average spacing between
molecules?
probably NO2(comprised mostly of N and O)

1. Compare the terminal velocity of a 10 nanometer particle with
a 100 nanometer particle. Which one “falls” through the air faster?
What are the approximate speeds of both particles as they “fall?”
Use Equation 2.1 on page 35 in your analysis. Also use Pg = 1.225
Kg/m3 and Pp = 1000 Kg/m3.

The human body contains about 10^(14) cells, and the diameter of
a typical cell is about 10 micrometers. Like all ordinary matter,
cells are made of atoms; a typical atomic diameter is 0.1
nanometers. I have all of the correct answers, but I do not know
how to get to these answers or solve them on my own. I would like
to get explanations (why?) and see how it should be done (math
being done). a) How does the number...

Each "2p" electron deep inside a Tungsten atom is influenced
mostly by 74 protons in the nucleus (treat as a point), and the 4
electrons (treat as shells around the nucleus) which are interior
to it (2 in 1s and 2 in 2s). How fast does one of these "2p"
electrons need to be moving, to travel around a circular orbit with
radius 3.158[pico-meter]?

The allowed energy levels of the hydrogen atom are described by
the following expression:
En=−2.17868×10^−18J(1/ n^2)
where n is the quantum number of the energy level. The Balmer
series that is observed in the line spectrum of hydrogen
corresponds to transitions that end in the n = 2 level. Determine
the wavelengths of the first 5 lines in the Balmer series.
