I answered the first part of the question where I estimate the radius of ##O_{2}## is ##\approx 1.5 \times 10^{-10} \ \text{m}##:
$$ p = \frac{KT}{l 4 \pi r^{2}} = \frac{(20+273.15)(1.38\times 10^{-23})}{(0.1)(4\pi)(1.5 \times 10^{-10})^{2}} = 0.143 \ \text{Pa}.$$
The confusion arises on the...
Hello Everyone!
I am interested in examining the case of an isolated Einstein Solid (ES) with a decreasing number of oscillators. The total amount of energy of the ES is considered fixed. Whenever an oscillator abandons our model, it "leaves behind" the amount of energy it contained, so that the...
Fermi-Dirac distribution function is given by
f(E)=(1)/(Aexp{E/k_{B}T}+1)
here A is the normalization constant? How we can get A?
E is the energy, k_{B} is the Boltzmann constant and T is the temperature.
thank you
