Points: 2
Answers:
- Choice: It is small when the density of matter ($n$) is small.
Validity: correct

At high energy (large $E-\mu$ values), we can use the Botzmann,
Fermi-Dirac, or Bose-Einstein disributrions to study any gas of
particles (e.g., photons, electrons,\ldots)
Size: Auto
Points: 2
Answers:
- Choice: 'This is true because this corresponds to the low density limit. '
Validity: correct
- Choice: >-
This is false because the three distributions do not converge to one
another at high energy.
- Choice: >-
This is a very good question. I wil make sure to read page 598 of the
slides posted on SLACK to understand the answer.

Consider a bosonic particle extracted from a large distribution of the same
particles. A specific measurement shows that its energy is 1~eV below the
chemical potential of the distribution. What can you conclude?
Size: Auto
Points: 2
Answers:
- Choice: 'The particle is very stable. '
Validity: incorrect
- Choice: 'The entropy of the particle is very small. '
Validity: incorrect
- Choice: >-
Researchers who performed the measurements should sign up for PHYS-2350
at RPI: their measurement is clearly wrong.
Validity: correct
