The system above has two distinguishable particles, each can be
in either of two boxes. The system is in thermal equilibrium with a
heat bath at temperature, T. The energy of the particle is zero
when it's in the left box, and it is
when it is in the right box. There is a correlation energy term
that increases the system energy by
if the particles are in the same box.
If the particles are indistinguishable how many microstates will...

2. There is a system with infinite evenly spaced energy levels, with the ground state at true zero. The spacing is cquivalent to 100cm-1. The levels are doubly degenerate in the ground state, then singly degenerate, then doubly degenerate, etc. (Please see the figure.) The partition function can be found both numerically and analytically. At 27C, how many levels must be included in a summation to ensure numerical accuracy to 10%? How many levels must be included in...
