Homework Statement 1. Estimate the concentration of oxygen in the Earth's atmosphere (in molecules / m^3), at room temperature and at sea-level, assuming the fact that oxygen comprises 21 percent of the Earth's atmosphere by volume. 2. If you were to place a perfect oxygen sensor of...

Figured it out. For anyone who finds this thread: Once you have Ω_{A} and Ω_{B} Use S = kln(Ω_{A}) +kln(Ω_{B}) Then we know that the most probable macrostate is when, \frac{δS}{δq_{A}} = 0 So just solve for q_{A},then use it to solve for q_{B}. I got q_{A} = \frac{200}{3} q_{B} =...

Homework Statement Consider two Einstein solid A and B with N_{A} = 200 and N_{B} = 100. Suppose now that the oscillations of solids A and B are different. The energies of oscillators in solid A are measured in units of ε_{A}, so that the energy of solid A is U_{A} = q_{A} ε_{A}. Likewise...

Homework Statement I was given a sample of 5000 points from an ellipsoidal blob (in 3D) that has some orientation. Assuming that each point has equal mass, I was asked to calculate the inertia tensor of this blob, then find the principal axes to determine the orientation of this blob...

Homework Statement Estimate the number N of molecules in a few grams of matter. Explain why in that case ln (N) is of the order of 50 whatever the chemical composition. Homework Equations M = m/N where M is the molecular mass The Attempt at a Solution I'm really unsure about the entire...
