Please explain each step as thoroughly as you can as I am quite confused with this unit. Thanks in advance! 1. A gas in a container is at a constant temperature T. The molecules have two vibrational energy states, the higher of which has energy 0.88 kBT. There are 3000 molecules in this higher energy state and approximately 5500 in the lower state. What is the energy of the molecules in the lower state? 2. Spherical particles have a density...

Consider a gas of diatomic molecules (moment of inertia I) at an
absolute temperature T. If Eg is a ground-state energy and Eex is
the energy of an excited state, then the Maxwell-Boltzmann
distribution predicts that the ratio of the numbers of molecules in
the two states is nexng=e−(Eex−Eg)/kT. The ratio of the number of
molecules in the lth rotational energy level to the number
of molecules in the ground-state (l=0) rotational level is
nln0=(2l+1)e−l(l+1)ℏ2/2IkT. The moment of inertia of...
