i. A two-level system has a ground level with four degenerate states and an excited level with two degenerate states at 450 cm−1 above the ground level. Please plot the ratio of the number of particles occupying the excited level to the number of particles occupying the ground level as function of temperature (Make sure that the end points and curvature are accurate but anything else can be qualitative).

How do i need more Info? This is all given to me

Find the lowest two "threefold degenerate excited states" of the three-dimensional infinite square well potential for a cubical "box." Express your answers in terms of the three quantum numbers (n1, n2, n3). Express the energy of the two excited degenerate states that you found as a multiple of the ground state (1,1,1) energy. Would these degeneracies be "broken" if the box was not cubical? Explain your answer with an example!
