Statistical Mechanics. We have a system of N bosons with zero spin. Each boson can have two states of energies 0 and E. Let μ be the chemical potential of the system and suppose that N >> 1. a) Determine the temperature T so that the mean population of the ground state is twice that of the excited state of energy E. Express kT only in terms of N and E. b) What would be the corresponding temperature T′ if the particles obeyed Boltzmann statistics? Compare both results and discuss them physically.

- What is the rms speed (Urms) of an He atom at 28C? Solve and explain.arrow_forwardYou are performing work as an assistant to a cosmology professor. She asks you to estimate the temperature of the Universe at a time after the Big Bang when neutral atoms could form from the plasma and the Universe became transparent. She tells you that the energy required to excite an atom is on the order of 1 eV. She suggests you use the Boltzmann distribution function e-E/k BT to find the order of magnitude of the threshold temperature at which 1.00% of a population of photons has energy greater than 1.00 eV.arrow_forwardCould someone explain to me in detail why bringing a crystal substance to absolute zero isn't possible? I know it's not because of quantum mechanics and uncertainty like some people say, because particals at their lowest zero-point will have a temperature of exactly 0 K, even though they're still experiencing motion. From what I've gathered, the energy or time required to pull it off is infinite, but I can't find any equations or clear explanations as to why or how that is. And I also don't know if there's any other reasons beyond that. If you could give me a thourough a breakdown for how absolute zero is impossible as you possibly could, I'd greatly appreciate it. Take as much extra time as you need. As long as it's detailed and correct I'm happy. Though ideally I would before it come in before the end of the day.arrow_forward
