The Einstein coefficients are fixed probabilities per time associated with each atom, and do not depend on the state of the gas of which the atoms are a part. Therefore, any relationship that we can derive between the coefficients at, say, thermodynamic equilibrium will be valid universally. At thermodynamic equilibrium, we will have a simple balancing, in which the net change in the number of any excited atoms is zero, being balanced by loss and gain due to all processes.

WebThe Stefan–Boltzmann law describes the radiation emittance R * of an IBB R * = σT4, where σ equals to 5.67 × 10 –8 W/ (m 2 K 4 ). The sun's surface temperature can be determined using the Wien's law λmax = b / dT, where b = 2.90 × 10 –3 m K. Combining these two formulas, we obtain Executing calculations, we arrive at R * = 6.4 × 10 7 W/m … WebIn the mid to late 1800s, James Clerk Maxwell and Ludwig Boltzmann figured out the answer to this question. Their result is referred to as the Maxwell-Boltzmann distribution, because it shows how the speeds of molecules are distributed for an ideal gas.
